Mark Tremonti and Myles Kennedy take PG through their Alter Bridge road rigs.
PG’s John Bohlinger hung with Alter Bridge’s two-man guitar army, Mark Tremonti and Myles Kennedy, before their sold-out show at The Orpheum Theater in Memphis. Tremonti and Kennedy showcased some beautiful signature Paul Reed Smith guitars, as well as a not-yet-released PRS signature amp.
Thanks to techs Dave Pate and Scott Davis for their help with the details.
Brought to you by D’Addario Strings.
Brown Sound
Not surprisingly, Tremonti exclusively plays his Paul Reed Smith Mark Tremonti Signature.
The first is an early model from around 2002, sporting a signature brown burst with a tremolo bar. All guitars have D’Addario strings, though gauges vary by tuning. This one is tuned to Eb with 49–38– 28–17–13–10. Tremonti uses Dunlop Tortex 1.3 mm picks.
Spare Some Change?
This is Dime—short for Dimebag—Tremonti’s second PRS single-cut with a whammy bar.
Don't Call Me Daughter
This is Stella, named after Tremonti’s two-year old daughter. Tremonti and Paul Reed Smith came up with the body design together. PRS isn’t set up to mass-produce this shape, so there won’t be a wide-scale production.
Bearded Beauty
This “Fenton” graphic guitar is one of 20 produced. This was a 20th anniversary model with original art painted by Joe Fenton.
Outlaw Style
H.A. (Hell’s Angels) was the second prototype Tremonti signature made by PRS. The pickups are early prototypes.
Mark Tremonti's Pedalboard
Tremonti’s signal starts with an Evidence Audio ‘The Reveal’ cable from his guitar to his pedals, and Mogami W2319 and Square Plug SP5 plugs for patch cables. Pedals include a Morley “Mark Tremonti” Signature Wah, Ibanez TS808HW, Boss TU-3, Boss OC-5, Digitech The Drop, MXR Smart Gate, Mark Tremonti prototype signature chorus/vibrato, and a Lehle Little Lehle III true bypass loop pedal. There’s also a G-Lab SD-1 running into the amp’s effects loop.
The Big Reveal
The PRS MT 100 Mark Tremonti Signature 100-watt three-channel head has not been officially released yet, but Tremonti has been touring with it for a while, as a shake-down cruise.
Crushin' Cabs
He runs this tube-driven beast into two oversized Mesa 4x12 cabs, loaded with Celestion British V30s wired at 8 ohms. The amp uses a Kikusui PCR1000M voltage regulator/power conditioner, plus there’s a Lehle P-Split for splitting signals to main and backup heads.
The Four Horsemen
Kennedy tours with four of his new PRS Signature guitars. The ones finished in natural and white are both tuned to Eb or Eb with a dropped C#, depending on the song. The signature is a bolt neck, T-style guitar with 10” radius, and Narrowfield pickups. All guitars are strung with D’Addario Light Top/Heavy Bottom Strings (.010-.052).
Dr. Hoo
Kennedy reveres owls for their wisdom and adaptability. PRS has a long-standing tradition of using bird silhouettes for inlay markers, so it only made sense that Kennedy and PRS would incorporate their collective avis admiration in the signature model.
Green Machine
Kennedy’s green Signature is tuned to A#–G#–C#–F#–A–#D#, and G–#G–#C#–F#–A#–D#, depending on the song.
Back(up) In Black
Kennedy’s black Signature is strictly a backup in case there are problems with any of the others.
Diezel Power
Kennedy runs two Diezel heads: a Diezel VH4 and a Diezel Herbert. The amps run into two Diezel 4x12 cabs loaded with green Tone Tubby Hempcone 40/40 Ceramic speakers.
Myles Kennedy's Pedalboard
Kennedy runs his MXR Carbon Copy and an EarthQuaker Devices Dispatch Master in the VH4’s clean loop. Over on his pedalboard, there’s a Dunlop MC404 CAE Wah, Boss TU-2 tuner, Electro-Harmonix’s Nano POG, Lizard Queen, and Freeze, a Ceriatone Centura, Strymon Deco, Line 6 MM4, and a Boss RV-6.

Warm Audio Introduces the WA-C1 Chorus Vibrato & Pedal76 Compressor Pedal
Introducing the WA-C1 Chorus Vibrato and Pedal76 from Warm Audio, faithful recreations of legendary studio gear in pedal form. The WA-C1 offers lush chorus and vibrato tones with modern upgrades, while the Pedal76 delivers professional studio compression for guitar and bass players. Available now at authorized retailers worldwide.
Warm Audio, the leading manufacturer of faithful recreations of legendary recording gear and guitar pedals, today announces the release of two new pedals. Introducing the WA-C1 Chorus Vibrato, a faithful recreation of the most celebrated chorus in guitar pedal history with a 100% analog preamp and additional no-compromise features for exploring legendary modulated tones. Additionally, Warm Audio is releasing the Pedal76, an all-analog, transformer-balanced FET compressor pedal that accurately reproduces one of the fastest and most powerful studio compressors of all time known for ultra-responsive dynamic control with rich analog tone. The WA-C1 Chorus Vibrato (MSRP $189 | 219 € inc.VAT | £189 inc. VAT) and Pedal76 (MSRP $269 | 299 € inc. VAT | £259 inc. VAT) are available at launch at authorized retailers worldwide.
“This launch is exciting and unique for us. We’ve applied the Warm Formula to deliver the OG ofbold chorus sounds and we’re thrilled to authentically bring that tone back to pedalboards. Additionally, we’re leveraging our 10-year expertise in 76-style studio compression to create a compressor pedal that not only delivers premium studio performance but is loaded with additional features & controls to make it a heavy-hitter in its own right,” said Bryce Young, founder & president of Warm Audio. “The WA-C1 Chorus Vibrato not only brings back that iconic, lush chorus sound and rich, three-dimensional vibrato, but the high-quality preamp inside delivers pure, all-analog tone that just can’t be replicated by digital emulations.”
Young continues, “With Pedal76, we’re excited to bring the high-quality circuit and premium components of our WA76 studio compressor to pedalboards for controlling dynamics on stage without squashing character. With the added features and stage-friendly circuit, we’ve ensured that Pedal76 plays nice with both your rig and a live sound mixing board, while providing additional boost as needed. We’ve intentionally designed Pedal76 to be the ultimate all-analog compressor pedal for guitarists and bass players.”
WA-C1 Chorus Vibrato
The WA-C1 is built upon a true-to-original circuit design and a premium, 100% analog preamp that lives up to the demand for ultra-responsiveness on stage. Matched to the renowned original, the all-analog preamp features level control that adds bite, depth, and even some natural compression to guitar tones, even in bypass mode. The chorus setting features separate depth and rate controls to expand beyond the limitations of vintage units while preserving the legendary tone. These separate controls (vs. the vintage “intensity” control) allow for adjusting depth and rate independently to dial in more depth and slower rates for even richer chorus tones. Just like the vintage units, the WA-C1 delivers lush midrange depth and detail associated with proper Bucket Brigade Device analog chorus pedals and has a stereo output. When it’s time to add true wobble, the vibrato section of the WA-C1 is authentic to the original pedal delivering added speed and bounce to the tone. Leveraging a modern BBD chip recreation with other premium components and boutique build quality, the WA-C1 is carefully clocked to match the depth and rate of the original pedal to reproduce the detail expected from the most sought-after vintage pieces.
While maintaining true-to-original tones, the WA-C1 delivers some modern upgrades to the experience. The WA-C1 features a selectable impedance on the back panel to select between the vintage input impedance of 50k ohm and a 1.1M Hi-Z setting that allows players to compensate for higher impedance of guitars vs. keyboards and to add clarity to the high-end on guitars, if desired. This switch also works in bypass mode to maintain clarity. To deliver the appropriate voltage associated with the original, the WA-C1 is supported internally with a dualDC-DC voltage converter to deliver robust power when using a standard external 9V power supply. The WA-C1 adds a flashing LED for effect monitoring, showing which setting is engaged along with the rate of the modulation.

Pedal76
For over 10 years, Warm Audio has been building a premium, award-winning 76-style studio compressor, the WA76. With expertise in building this circuit and knowing what drives the sought-after tone of the most coveted dynamic control, Warm Audio now delivers truly professional, full-feature compression for the pedalboard. Pedal76 features a custom CineMagtransformer that is spec’d to duplicate the performance and tone of the studio units in a pedalboard-friendly format. Premium capacitors, resistors, and transistors round out a circuit that cuts no corners in delivering an authentic studio experience on stage. The added harmonic depth from the FET circuit and rich tone preservation from the custom transformer blend perfectly to recreate the ultimate compressor for guitar and bass players. Pedal76 features Attack & Release, Ratio, and Input controls, critical for taming unwanted changes in volume on stage. Pedal76 also has added features optimized for live performances including an external switch for true and buffered bypass operation, ensuring the compressor plays nice in your rig. Switches for input sensitivity, ground/lift, pad engagement and high/low gain modes (both for DI operation) provide added utility at gigs or in the studio. The separate balanced (DI) out also sends proper signal to the mixer or live recording rig, with the high gain mode adding grit and rich transformer tone.

Keeley Electronics - Octa Psi Transfigurating Fuzz - Sarah Lipstate Performance - YouTube
Seldom before has an innocent-looking pedal offered such devilish delights.
Combining a ferocious fuzz circuit with remarkably powerful pitch-shifting capabilities, Keeley’s new Octa Psi pedal makes it easy to blow your mind … and have a ton of fun in the process.
It’s capable of creating pleasing and/or demented intervals, subtle harmonizing, expansive octaves up and down, and swooping pitch changes—all turbocharged by one of the gnarliest fuzzes this side of Armageddon.
Simply Psychoactive ... By Intent
If you’ve ever craved a user-friendly freakout, this is it. With just five knobs, two 3-way toggle switches, and a pair of footswitches—as well as an expression pedal input—the Octa Psi presents a comfortable, inviting portal to a universe of crazy sonic exploration.
That’s exactly what Robert Keeley intended from the moment he started designing the Octa Psi.
“The finished pedal is true to the original idea that I had in November 2021,” Keeley says. “I wanted it to have a high-gain vintage Muff, all-analog and all-transistor, going into an octave pitch shifter—something in the neighborhood of a Pitch Fork or POG. And then when I added the expression pedal function, it could resemble a whammy.”
Ah yes, the expression pedal input. Linking the Octa Psi with a standard expression pedal opens the door to a whole new dimension of pitch shifting mayhem. Rest assured, you don’t have to use an expression pedal to derive crazy fun from the Octa Psi. But it sure helps.
With all of the pedal’s deep functionality, Keeley felt that simplicity would be a key factor in broadening its appeal, starting with this elemental item: “From the get-go I wanted it to have order switching, allowing the fuzz feeding the pitch shifter or vice versa, because it gives you two distinctly different sounds if you have pitch going before or after the fuzz. And it had to be pretty effortless for the player to switch the order on the fly. And I wanted it to be easy to switch between using it either as a harmonizer or as an all-wet octave-down thing.” That desire for ease-of-use, even in the middle of a live gig, drove the design of the pedal’s controls and functions.
“I wanted to come up with something that Jack White, Steve Vai, or Frank Zappa would have fun with.”
It Ain't Easy to Create Easiness
The Octa Psi exemplifies an old adage: Sometimes a simple solution can be the most difficult to achieve. “I knew this was going to be a challenging project,” Keeley admits. “It’s very tough to combine a high-gain, full-analog distortion with a DSP [digital signal processing] section in one box. It took a long time to get the switching just right. It was particularly difficult because the Octa Psi’s analog and DSP sections are so intimately entwined. You can’t have gaps in the audio when you’re switching back and forth. Those kinds of complications drove us crazy.
“We also addressed a lot of issues that have raised concerns about other products on the market. The Octa Psi is a true-bypass pitch shifter, and it has our killer buffer system as well. There’s nothing else out there like this, so we had to figure it all out for ourselves.“
An essential challenge: voicing the fuzz so that it would sound great as a standalone effect, while also playing nicely with the Octa Psi’s harmonizer functions. “You would think that the fuzz was easy, but it was actually one of the last things we ironed out,” Keeley notes. “I had to ask myself, ‘Do I want this to be a bass-y fuzz?’ Probably not, since the pitch shifter can add octave down. But it’s got to be an amazing sounding fuzz if I want people to consider buying it. It has to sound great when compared to any Big Muff, and it has to effortlessly pair with a DSP section. So, getting the fuzz just right turned out to be the hardest part!”
The pedal design process also encountered some last-minute wrinkles. “The ramping and momentary switching capability was the last big feature that was added. That ramping function is like having an onboard expression pedal. We talked about it in the beginning of the process with Sarah Lipstate [also known as the artist Noveller], when Aaron Pierce [a key member on the Keeley team] was working on the initial concept. Later, Michael Kaye—the guitar tech for Pete Townsend and Trey Anastasio—asked, ‘Does it have momentary switching?’ and I was like, ‘Oh crap, I forgot about that!’” Keeley laughs.
The How-To Guide for Octa Psi's Hidden Features
For all of its readily accessible capabilities, the Octa Psi boasts several essential features that can only be accessed by using more than a single knob or switch. To unlock these features, it helps to have a few simple, specific instructions. For this reason, Keeley has included a brisk, handy primer on the back of each pedal. The Octa Psi’s key “hidden features” include:
- EFFECT ORDER: You can instantly switch the effect order by simultaneously holding the octave and fuzz footswitches.
- WET/DRY SELECTION: Double-click the blend control knob for switching between wet/dry blending or wet-only.
- MOMENTARY/LATCHING OPTION: Press and hold the fuzz footswitch to choose between momentary or latching operation. This is crucial if you plan on using the Octa Psi’s adventurous pitch shift ramping capability: the output signal begins with the initial note(s) you’re playing, and then veers up or down to the effected pitch. The ramp speed—i.e. how quickly this veering effect lasts—is controlled by….
- RAMP SPEED: If you’re using pitch shifting in the momentary mode, you can adjust the ramp speed by pressing and holding the octave footswitch down, then adjusting the blend knob control.
Part of an Ongoing Evolution
The Octa Psi underscores the continuing evolution of Keeley’s product line. In particular, it benefits from a pair of preceding Keeley devices: the I Get Around Rotary Simulator pedal and California Girls Twelve String Simulator—two pedals that were released in summer 2024 as exclusive offerings for the U.S. retailer Sweetwater, timed to coincide with The Beach Boys documentary on Disney+.
“That Beach Boys project did so much to help the DSP side of the Octa Psi,” says Keeley. “I got audio analyzers in so I could study the signals. We found out that we had to make our power supplies better because of the Beach Boys pedals, and that revolutionized our design. Everything that comes out since the Beach Boys pedals is going to sound even better. Plus, it was a lot of fun working with Sweetwater and JHS Pedals.”
Interestingly, for the Octa Psi project, the Keeley design team did not rely on much input from the company’s long list of affiliated artists. “I didn’t really have an artist that is a pitch/fuzz guru, so I had to keep it pretty much to ourselves. I knew that it had to be very musical—as musical as we could get it. And thankfully we have a team that can make this happen.”
The Keeley product development squad includes electrical engineer Craighton Hale, programmer Aaron Tackett, and Aaron Pierce—the “golden ears” member of the design group who helps analyze the sounds. “I’m just one part of the team of engineers that help make the products come to life,” Keeley notes.
Fun for Everyone
In the end, Keeley hopes that the Octa Psi pedal finds new and unconventional uses in the real world. “I wanted to come up with something that Jack White, Steve Vai, or Frank Zappa would have fun with—something that does all the crazy pitch-shifting with a purpose. And I’m hoping that musicians of all types will be attracted to this. People who want to distort their drums or bass or synth, and then start taking advantage of the pitch shifting. It’s almost like you get a great fuzz with the pitch shifter for free. On the other hand, I wouldn’t be surprised if some people use just the pitch shifter, if they’re not a fuzz maniac. You can get a lot of fun out of it without an expression pedal.”
Whether you’re a brazen sonic adventurer, or simply looking for a great-sounding dual function fuzz/harmonizer pedal, the Octa Psi offers a galaxy of tones for your arsenal.
