Starting at top right, Bryan Beller’s board has a pair of Xotic EP Boosters to bring up the output of his two passive instruments to match his Lull bass. Next comes a Demeter COMP-1 Opto Compulator that’s always on, followed by a TC Electronic Hall of Fame Reverb, Boss CE-2B Bass Chorus, Boss DD-3 Digital Delay, and a TC Electronic Flashback Delay/Looper. Moving to the bottom left, there’s a Boss OC-2 Octave and an Xotic Bass BB Preamp (Beller’s main overdrive). The Darkglass Electronics Vintage Microtubes and MXR M109S Six Band EQ are used for a beefier, RAT-like sound. Then there’s an EHX Micro POG set to an octave up and an old DigiTech X-Series Bass Driver that pushes the BB Preamp and runs into the Dunlop 105Q Cry Baby Bass Wah pedal (white), giving vocal-like sweeps more definition. Beller also has a Dunlop DVP3 Volume (X) Volume and Expression pedal and a Boss TU-2 Chromatic Tuner. Beller has incorporated the Behringer FCB1010 MIDI controller into his rig so he can provide some “low-rent Geddy Lee” moments in the set via a Roland JV-1010 64-Voice Synth Module.

Using the Raven Labs MDB-1 Mixer/Direct Box/Buffer for his pedals and running the Roland JV-1010 into his amps allows Beller to employ both his bass and the synth module at the same time.

Nitty Gritty Dirt Band’s Jeff and Jaime Hanna
Jeff Hanna
Jeff Hanna, who co-founded the Nitty Gritty Dirt Band in 1966, runs his acoustic guitars through a Fishman Aura Spectrum DI and a Boss TU-3 Chromatic Tuner. The electric side of his board includes another Boss TU-3, a Paul Cochrane Tim V3 Overdrive, a Keeley Katana Clean Boost, a J. Rockett GTO, a Keeley-modded Boss TR-2 Tremolo, and a Keeley Mag Echo.
Jaime Hanna
His son Jaime combines acoustic and electric pedals on one board. The acoustic side features a Fishman Aura Spectrum DI, Boss TU-3 Chromatic Tuner, and a Radial JDI direct box as a back-up. For electric, there’s an Ernie Ball volume pedal that feeds a TC Electronic tuner. The main out hits a Mesa/Boogie Stowaway Class-A Input Buffer, a Keeley Compressor, a Paul Cochrane Tim Overdrive, a J. Rockett Archer, an MXR Super Badass Distortion, a Boss GE-7 Equalizer modded by Nashville’s XTS, and a Line 6 M9 Stompbox Modeler Multi-Effects pedal. A Truetone 1 SPOT PRO CS12 provides the juice.

Shredder Diamond Rowe keeps things succinct. Her stage setup features an always-on Ibanez TS9 Tube Screamer and a DigiTech Whammy for pure fun and note obliterating. A pair of utilitarian Boss stomps—an NS-2 Noise Suppressor and TU-3 Chromatic Tuner—keep her strings clean and accurate. There’s also a Voodoo Lab Pedal Power ISO-5 and Ground Control Pro MIDI Foot Controller.
In a separate rack, Rowe hides her “freak tone” patch. There lurks a Boss RV-6 Reverb, Boss DD-7 Digital Delay, Boss CE-5 Chorus Ensemble, and a MXR Uni-Vibe Chorus/Vibrato, plus a pair of tucked-away MXR Carbon Copy Analog Delays. The rack toys are fired by a Voodoo Lab Pedal Power 2 Plus.

Marcus King
Roots powerhouse MarcusKing runs his guitar’s cable into a Dunlop Volume (X) 8. Then his signal hits a Dunlop Cry Baby Wah, an MXR Booster, an Ibanez TS9 Tube Screamer, a Tru-Fi Two Face Fuzz, MXR Micro Chorus, Dunlop Rotovibe Chorus/Vibrato, MXR Phase 100, Tru-Fi Ultra Tremolo, Dunlop Echoplex Delay, MXR Reverb, and a Radial Shotgun signal splitter and buffer. Juice? That’s via a Voodoo Lab Pedal Power 3 Plus.

Foo Fighters’ Chris Shiflett
The mega-rockers’ Chris Shiflett starts his pedalboard with an EHX Micro POG, followed by a JHS Muffuletta, an MXR Flanger and EVH Phase 90, an EHX Holy Grail reverb, a Strymon Deco, and a Klon KTR. The next row sports a Boss CE-2W Waza Craft Chorus, a couple of Strymon TimeLines (one for each amp), and down below is a trio of Xotics—an EP Booster, SP Compressor, and an XW-1 Wah. Utilitarian boxes include a Lehle Little Dual II Amp Switcher, a Palmer PLI-05 Line Isolation Box, a Boss FS-5L Foot Switch (to toggle between clean and dirty on his Friedman Brown Eye), and a TC Electronic PolyTune.

Mammoth WVH's Wolf Van Halen
Wolf Van Halen brought every EVH pedal (aside from the 5150 Overdrive) for his band’s 2022 tour. The Dunlop EVH95 Cry Baby Wah gets a workout for the solo of “You’ll Be the One.” The MXR EVH 5150 Chorus and the MXR EVH Phase 90 have become interchangeable for him. The MXR EVH117 Flanger gets sprinkled in, and for the solo on “Distance,” he always uses the Boss DD-3 Digital Delay and the EarthQuaker Devices Afterneath. An acoustic DI and tuner consume the rest of the real estate.

Ronnie Ficarro
Ronnie Ficarro’s bass stomp station hosts a trio of EVH-inspired pedals: an MXR EVH 5150 Chorus, a MXR EVH 5150 Overdrive, and the MXR EVH Phase 90—plus an EHX Pitch Fork for approximating the low B roar that Wolf recorded on the song “Epiphany.” The nondescript silver box is a channel switcher for his Fender Super Bassman, and a Peterson StroboStomp HD does the tuning.

El Ten Eleven’s Kristian Dunn
As half of this bass and drums duo, Kristian Dunn used to use three pedalboards, crouching down and manipulating settings all night. Today, he depends primarily on a Line 6 M9 Stompbox Modeler, although it’s two Boomerang III Phrase Samplers that make an El Ten Eleven show happen. In line, they’re separated by the DigiTech Bass Whammy. Dunn routes his signal this way so he can use the Whammy to shift octaves or keys on entire loops in Phrase Sampler one. The second Phrase Sampler, after the Whammy, allows him to pitch-shift specific loops without impacting the whole song or other loops. The Strymon TimeLine conjures precise repeats and specific delay settings not in the M9. The EHX Superego Synth Engine is a secret weapon, for reverse-sound passages. When he holds down the freeze function and plays the next note, it’s not audible until he releases the switch, and then the ongoing audible note blends into the second note. Cool, right? The remaining two pedals are a Nu-X NFB-2 Lacerate FET Boost and a Marshall GV-2 Guv’nor Plus. His tuner: a Boss TU-3 Chromatic. A Custom Audio Electronics RS-T MIDI Foot Controller makes Dunn’s scene changes easier, talking with the M9 and Strymon to alleviate some tap dancing.

Shinedown’s Zach Myers
For the Shinedown guitarist, everything starts at the Fractal Audio Axe-Fx IIIs—a main and a backup. There are four channels of Shure UR4D+ wireless units (three for electric and one for acoustic). An AES digital out runs to an Antelope Audio Trinity Master Clock and Antelope Audio 10MX Rubidium Atomic Clock. This helps fatten the fully stereo, digital rig by converting it to analog. After that, IRs off the Axe-Fx (left and right) channel into a pair of Neve DIs that then feed a Fryette G-2502-S Two/Fifty/Two Stereo Power Amplifier. (There’s another for backup.) And finally, parallel signals go to two ISO cabs and two Universal Audio OX Amp Top Box reactive load boxes. Altogether, there are eight channels of guitar.
While tech Drew Foppe handles the racks, Zach still has some control at his toes via a Dunlop MC404 CAE Wah, DigiTech Whammy 5, Ernie Ball 40th Anniversary Volume Pedal, and the Fractal Audio FC-6 Foot Controller. A Voodoo Lab Pedal Power 2 Plus gives life to these pedals.

Shinedown's Eric Bass
Eric Bass’ Prestige basses hit the Shure UR4D+ wireless units (similar to Myers, he has three channels for electric and a channel for acoustic), then a Neve DI, and then a Radial JX44 signal manager that feeds into an Ampeg SVT-7 Pro for clean tone (with an extra for backup).
His onstage pedalboard includes a Dunlop 105Q Cry Baby Bass Wah, a DigiTech Bass Whammy, and an MXR M299 Carbon Copy Mini Analog Delay. The ‘Gas’ switch engages a Mojotone Deacon, and a Radial SGI-44 1-channel Studio Guitar Interface connects with his rackmount JX44, while a Boss TU-3W Waza Craft Chromatic Tuner and Voodoo Lab Pedal Power 2 Plus complete the lineup.

Blueser Hannah Wicklund’s pedalboard is stacked for bruising. Once the signal gets past her MXR Talk Box and Dunlop JC95 Jerry Cantrell Signature Cry Baby, it hits the channel switch for her Orange head. That stays in overdrive mode for about 75 percent of her set, which she says gives her sound its grizzly-bear lows. Next up is a classic—a Boss BD-2 Blues Driver. But this one has a Keeley mod that opens up the low end and keeps mids and highs better defined. The BD-2 gets some atmospheric help via a Dunlop EP103 Echoplex Delay, and the J. Rockett Archer also pairs with the BD-2. There’s an MXR Micro Flanger and an EHX Nano POG, a T. Rex Room-Mate Tube Reverb (on a hall setting), and a Peterson StroboStomp HD, plus an MXR Carbon Copy and a Keeley Rotten Apple OpAmp Fuzz.

Code Orange’s Reba Meyers
Reba Meyers’ tone starts with her signature ESP LTD RM-600 guitar and her 5150 head, but from there her sound is processed via a Fractal Audio Axe-Fx III run through the effects loop of her amp and used to coordinate channel switching. Meyers notes that for some songs she uses it only as a gate, while for others she adds in precise modulation, delay, reverbs, and “noise.” The rest of the rack features a Two-Notes Torpedo Captor X that she uses for cab sims and sending a pure, direct signal to FOH so they can mix that with the SM57 mic on the 4x12s. A Shure GLXD4 Wireless unit keeps her untethered and a RJM Mini Amp Gizmo uses MIDI to switch the amp via the Axe-Fx III.
Her actual board has two always-on pedals: the ISP Decimator II Noise Reduction and the Ibanez TS9 Tube Screamer. They’re joined by a Moog MF Ring Mod, a Boss PS-6 Harmonist, an AMT Electronics WH-1 Japanese Girl Optical Wah, and an Universal Audio Astra Modulation Machine. Everything is controlled by the RJM Mastermind PBC/10.

Joe Bonamassa
For his 2022 tour, Joe Bonamassa kept his pedalboard stocked with a Way Huge Smalls Overrated Special Overdrive, a Tone Mechanics/Racksystems Loop Box, a Tone Mechanics/Racksystems Splitter, a Fulltone Supa-Trem, a Hughes & Kettner Rotosphere, a Boss DD-2 Digital Delay, an MXR Micro Flanger, an Ibanez TS808 Tube Screamer, an EHX Micro POG, a Dunlop Joe Bonamassa Fuzz Face, a Lehle A/B/C Switcher, a Dunlop Joe Bonamassa Signature Cry Baby Wah in Pelham blue, and an on/off/fast/slow dual switch for his Mesa/Boogie Revolver rotating speaker cabinet. Juice came from a Voodoo Lab Pedal Power 2 Plus.

Exodus’ Gary Holt
Thrash-metallurgist Gary Holt trusts most of his switching to his tech, Steve Brogdon, who triggers everything with a rack-mounted Voodoo Lab GCX Guitar Audio Switcher that coordinates with a Voodoo Lab Ground Control Pro MIDI Foot Controller. The pedals in Brogdon’s care include a Boss SD-1 Super Overdrive, Pro Tone Pedals Gary Holt Signature Mid Boost, Maxon OD-9, MXR Bass Octave Deluxe, Maxon FL-9 Flanger, TC Electronic Corona Chorus, Boss NS-2 Noise Suppressor, and a Darta Effects Bonded by Delay. A BBE Supa-Charger provides juice.
Holt still stomps these boxes himself: a Does It Doom Doomsaw, Mooer Tender Octaver, Mooer Green Mile, and a Dunlop JC95SE Jerry Cantrell Special Edition Crybaby Wah. A Shure GLXD16 Digital Wireless Guitar Pedal System lets him rock untethered.

Dinosaur Jr.’s J Mascis
For at least 10-plus years, J Mascis has used a Bob Bradshaw-built Custom Audio Electronics switcher as his mission control. His longtime stomps include a Tone Bender MkI/Rangemaster-clone combo pedal made by Built to Spill’s Jim Roth (bottom right corner), Mascis’ first EHX Ram’s Head Big Muff Pi (top right), a vintage EHX Deluxe Electric Mistress, an MC-FX clone of a Univox Super Fuzz (lower right, blue box), a pair of ZVEX pedals—a Double Rock (two Box of Rock stomps in one) and a Lo-Fi Loop Junky (both bottom left), a Tube Works Real Tube Overdrive, a Moog Minifooger MF Delay, and a Boss TU-3S Tuner. His recently added pedals are a Homebrew Electronics Germania 44 Treble Booster (lower right), a JAM Pedals RetroVibe MkII, an Xotic SL Drive, a Suhr Jack Rabbit Tremolo, a Dr. Scientist Frazz Dazzler fuzz, an EHX Oceans 11, and a Dunlop Jimi Hendrix ’69 Psych Series Uni-Vibe Chorus/Vibrato. Everything receives juice from an MXR MC403 Power System or an MXR M237 DC Brick.

In collaboration with Cory Wong, the Wong Press is a 4-in-1 Press pedal features Cory’s personal specs: blue & white color combination, customized volume control curve, fine-tuned wah Q range, and a dual-color STATUS LED strip indicating current mode/pedal position simultaneously.
In collaboration with Cory Wong, this Wong Press is a 4-in-1 Press pedal features Cory’s personal specs: Iconic blue & white color combination, customized volume control curve, fine-tuned wah Q range, and a dual-color STATUS LED strip indicating current mode/pedal position simultaneously.
Renowned international funk guitar maestro and 63rd Grammy nominee Cory Wong is celebrated for his unique playing style and unmistakable crisp tone. Known for his expressive technique, he’s been acclaimed across the globe by all audiences for his unique blend of energy and soul. In 2022, Cory discovered the multi-functional Soul Press II pedal from Hotone and instantly fell in love. Since then, it has become his go-to pedal for live performances.Now, two years later, the Hotone team has meticulously crafted the Wong Press, a pedal tailored specifically for Cory Wong. Building on the multi-functional design philosophy of the Soul Press series, this new pedal includes Cory’s custom requests: a signature blue and white color scheme, a customized volume pedal curve, an adjustable wah Q value range, and travel lights that indicate both pedal position and working mode.
Cory’s near-perfect pursuit of tone and pedal feel presented a significant challenge for our development team. After countless adjustments to the Q value range, Hotone engineers achieved the precise WAH tone Cory desired while minimizing the risk of accidental Q value changes affecting the sound. Additionally, based on Cory’s feedback, the volume control was fine-tuned for a smoother, more musical transition, enhancing the overall feel of volume swells. The team also upgraded the iconic travel lights of the Soul Press II to dual-color travel lights—blue for Wah mode and green for Volume mode—making live performances more intuitive and visually striking.
Features
- True Bypass
- 4 in 1 functionality (volume, expression, wah, volume/wah)
- New dual-color STATUS LED strip indicating pedal mode and position in real time
- Cory’s custom volume curve and wah Q control
- Classic-voiced wah tone with flexible tonal range
- Active volume design for keeping lossless tone
- Separate tuner and expression outputs for more connection possibilities
- 9V DC or 9V battery power supply

Strymon BigSky MX
strymon.net
Strymon calls the BigSky MX pedal “one reverb to rule them all.” Yep, that’s a riff on something we’ve heard before, but in this case it might be hard to argue. In updating what was already one of the market’s most comprehensive and versatile reverbs, Strymon has created a reverb pedal that will take some players a lifetime to fully explore. That process is likely to be tons of fun, too.
Grinding out impressive DSP power via an 800 MHz tri-core ARM processor with 32-bit floating-point processing, the BigSky MX introduces seven brand-new reverb algorithms, allows users to load any compatible convolution reverb (or impulse response) as well as to use two reverbs simultaneously—in series, parallel, and split—plus it delivers several other mind-bending features. Given this wealth of goodies, it’s impossible to test and discuss every sound and function, but what we heard is exciting.
Infinite Space
The updated MX will look very familiar to those who know the original BigSky. The form factor is nearly identical, though the MX is a bit larger. Its control interface is similar too, albeit rearranged into a single row of knobs that looks more balanced. Rotary controls include decay, pre-delay, tone, mod, parameter 1, parameter 2, and mix. A value knob enables effect-level manipulation on the larger, clearer OLED screen. It also allows you to select between the older or “classic” algorithms from the original BigSky and the seven new ones. Three footswitches allow for preset selection, bank up or down (two switches pressed together), and an infinite hold/sustain switch that’s always available. The rotary “type” knob in the upper-left corner spins between 12 basic reverb voices. As with most things Strymon, many of these controls are multi-function.
Also very Strymon-like are the top-mounted, 5-pin DIN MIDI I/O connections, which come in handy if you want to maximize the pedal’s potential in a MIDI-controlled rig. But you can access more than enough right from the pedal itself to satisfy the needs of most standard pedalboard-based setups. A USB-C port enables computer connection for MIDI control via that route, use of the Nixie 2 editing app, or firmware updates.
There are stereo jacks for both input and output, plus a multi-function 1/4" TRS/MIDI expression jack for use with a further range of external controllers. The standard center-negative power jack requires a DC supply offering at least 500 mA of current draw.
It is utterly hypnotic and addictive once you settle in and work a little more intuitively.
Sky’s the Limit
The BigSky MX was, initially, a bit mind-boggling on account of the seemingly endless possibilities. But it is utterly hypnotic and addictive once you settle in and work a little more intuitively. Suffice it to say, the core quality of the reverb sounds themselves are excellent, and the sheer variety is astounding. Beyond the standard emulations, I really dug several permutations of the cloud reverb, the chorale mode (which adds tenor and baritone harmonizing tones), and bloom mode (which generates deep synthesizer-style pads), and I could have gotten lost in any of these for hours if there wasn’t so much more to explore. Among the highlights: There is now an option to pan reverbs across the stereo field. The MX also uses audio design concepts borrowed from tape delays to create rhythmic pattern-based reverbs, which is an excellent compositional tool.
The Verdict
This latest evolution of the already impressive and super-capable BigSky is the kind of pedal that could cause you to disappear into your basement studio, never to return. The sounds are addictive and varied and can be configured in endless creative ways. The programmability and connectivity are also superb. Additionally, the new algorithms weren’t added at expense of the old BigSky algos. There’s no doubt that it will be flat-out too much horsepower for the guitarist that needs a few traditional sounds and, perhaps, a few more spacious options. And it would be interesting to know what percentage of the pedal’s customers end up being synth artists, engineers, or sound designers of one kind or another. If you’re the kind of guitar player that enjoys stretching the sound and capabilities of your instrument as far as they will go, the BlueSky MX will gladly ride along to the bounds of your imagination. It may test the bounds of your budget, too. But in many ways, the BigSky MX is as much a piece of outboard studio gear as a stompbox, and if you’re willing to invest the time, the BigSky MX has the goods to pay you back.
This reader solicited the help of his friend, luthier Dale Nielsen, to design the perfect guitar as a 40th-birthday gift to himself.
This is really about a guy in northern Minnesota named Dale Nielsen, who I met when I moved up there in 2008 and needed somebody to reglue the bridge on my beloved first guitar (a 1992 Charvel 625c, plywood special). Dale is a luthier in his spare time—a Fender certified, maker of jazz boxes.
Anyway, we became friends and I started working on him pretty early—my 40th birthday was approaching, and that meant it was time for us to start designing his first solidbody build. If you stopped on this page, it’s because the photo of the finished product caught your eye. Beautiful, right? The 2018 CCL Deco Custom: Never shall there be another.
Old National Glenwood guitars were my design inspiration, but I wanted a slim waist like a PRS and the like. We used a solid block of korina to start, routed like MacGyver to get the knobs and switches where I wanted them. Dale builds all his own lathes and machines (usually out of lumber, y’all), as the task requires. This beast took some creativity—it’s tight wiring under that custom-steel pickguard. Many were the preliminary sketches. Four coats of Pelham blue, 11 coats of nitro. Honduran mahogany neck, Madagascar ebony fretboard with Dale’s signature not-quite-Super-400 inlays. He designed the logo; I just said, “Make it art deco.”
We sourced all the bits and bobs from StewMac and Allparts and Reverb and the like, mostly to get that chrome look I so adore. Graph Tech Ratio tuners, Duesenberg Radiator trem (had to order that one from Germany), TonePros TP6R-C roller bridge. The pickups were a genius suggestion from the builder, Guitarfetish plug ’n’ play 1/8" solderless swappable, which means I have about 10 pickups in the case to choose from: rockabilly to metal. And both slots are tapped, with the tone knobs serving as single- to double-coil switches. I put the selector on the lower horn to accommodate my tendency to accidentally flip the thing on Les Pauls—definite lifesaver.
Reader and guitar enthusiast, Cody Lindsey.
Dale offered to chamber this monster, but I said what doesn’t kill you makes you stronger. It weighs in at 11 pounds, if it’s an ounce. We carved the neck to match a ’60s SG, so it’s like the mini bat you get at the ballpark on little kids’ day. Easy peasy. 1 11/16" nut, 25" scale, jumbo frets, just 2 1/8" at the 12th fret.
Delivery in its lovely, hygrometer-equipped Cedar Creek case actually happened a month or two shy of my 41st, but hey, you can’t rush these things. We ended up with a studio Swiss Army knife; it does a bit of everything and does it effortlessly. A looker, too. Dale didn’t spend his career doing this kind of thing—he was in IT or some such—and I imagine he’s winding this “hobby” of his down these days, enjoying retirement with a bottle of Killian’s and a lawn chair at Duluth Blues Fest. But this guitar will live on as a marker of his skill and otherworldly patience. It sits at the head of the class in my practice room, welcoming any visitors and bringing a smile to my face every day. And Dale, my friend, I’ll be 50 before you know it....
Cody requested that Dale design an art deco logo for the guitar’s headstock.
This convenient, easy-to-use controller can open up an entire world of sonic shape-shifting. Here are some tips to either inspire you to try one or expand how you’re currently using this flexible, creative device.
If you’re not yet using expression pedals, you should consider them. They have the power to expand and control your sonic universe. For the uninitiated, expression pedals are controllers that typically look like volume or wah pedals. Of course, traditional volume and wah pedals are expression pedals, too, but they are dedicated to controlling only those two effects.
Modern expression pedals allow you to assign and control parameters of your stomps or modelers by moving the expression pedal as you would a volume or wah. Dunlop, Boss, Ernie Ball, Yamaha, Behringer, Mission Engineering, and other manufacturers make these handy devices.
Many, but not all, of today’s stompboxes and modelers have expression pedal inputs that allow for manipulation of one or more parameters of those devices. In the past, this required bending over and turning a knob, or trying to turn a small knob with your foot—both of which can hamper your playing. The freedom of an expression pedal is the control you have over more aspects of your sound, especially in a live setting.
Although some of the uses for expression pedals below can also be accomplished by creating multiple presets, that will not allow real-time control over the parameters like an expression pedal will. Here are some notes about expression pedal use that might get you thinking about how one could help you.
Delay Repeats: Controlling the timing of a delay with tap tempo is very common, but how about controlling the number of repeats? With an expression pedal, by setting the expression control on your delay to control the number of repeats, you can easily go from a few for your rhythm sound to more for your lead sound, and then back off again.
Reverb and Delay Mix: The mix control on reverb and delay pedals allows you to balance the amount of wet to dry signal that you hear. There is often a delicate line to having just the right amount of wet signal with these two effects. If you have too much, your sound can be washed out and undefined. Too little and it can be dry and lack space. The part you are playing, and the venue you are in, can also change the amount of mix you need for these effects. By using an expression pedal for the mix control on reverb or delay, you can alter the sound on the fly to compensate for the part and the room, including turning down the mix for busy parts and up for parts with fewer notes.“Some uses for expression pedals can also be accomplished by creating multiple presets, but that will not allow real-time control over the parameters like an expression pedal will.”
Modulation Depth: The depth of a modulation effect, like a phaser, can drastically alter your guitar sound. A light amount can create a feeling of subtle movement, while a heavy amount can give a thick, underwater-type sound. An expression pedal can help you create a constant feeling of change throughout a song, allowing you to build up and break down the depth for different sections as you see fit.
Tremolo Speed: While the speed of tremolo can often be controlled by tap tempo, using an expression pedal for the same parameter offers other creative uses of the effect. With an expression pedal, you can easily speed the tremolo up to make subtle increases to the energy of a part or slow it down to decrease the energy. You can also create drastic changes in the speed that sound like a fan accelerating or slowing down. Or you can abruptly turn the tremolo off. This last option can be an exciting way to end a song or part.
EQ Change: Every guitar player uses EQ to sculpt their sound—whether via the tone controls on your instrument or amp (modelers included), or a dedicated equalizer used as part of your rig. Subtle tweaks can help you do things like balance out different guitars, cut through the mix more, or compensate for a boomy stage. Real-time control of EQ with an expression pedal is more common in the modeler world than the amp and pedal world, but it does exist in both. For example, increasing the midrange can give you more clarity and cut for solos. Decreasing it can create a flatter sound that can help you stay in the mix with the rest of the band. An expression pedal allows you to have one setting and alter it for multiple situations or guitars as opposed to having separate presets.
While this is a very short list of options for expression-pedal use, it should give you a good place to start. The most important thing is to always be creative, have fun, and find your own voice. An expression pedal can help you do all three.
