A multiband EQ applied to reverb.
Learning the ins and outs of reverb can help you access a more creative approach to your mixes.
Hello, and welcome to another Dojo. This month I want to give you some creative ideas for using the oldest natural effect we have—reverb.
Reverb is a fundamental tool in every audio engineer’s arsenal, often employed to create depth, space, and ambiance. We use it to simulate the natural reflections of sound in physical spaces, like rooms, halls, or chambers, but the creative possibilities of reverb can extend far beyond that when used as part of a larger effects grouping, and can enable you to sculpt some downright captivating soundscapes.
One of the most common creative uses of reverb is to manipulate the perceived spatial dimensions of a reverberant sound. By adjusting parameters such as decay time, pre-delay, and diffusion, we can alter the size and character of the virtual space in which a sound appears to exist—like a gritty spring reverb imbuing a guitar riff with vintage charm or a shimmering granular reverb enveloping a synth pad in sparkling, crystalline reflections.
But what if we experiment with it in more creative ways by warping naturally occurring physical properties, or playing with pitch, or even side-chaining various parameters? Tighten up your belts, the Dojo is now open.
Reverb itself is the last of three basic events:
1. Direct sound: sound that reaches the listener’s ears directly without reflecting off of any surface.
2. Early reflections: Early reflections are the first set of reflections that reach the listener’s ears shortly after the direct sound, typically within the first 50 milliseconds. They contribute to the perception of spaciousness and localization (coming from the left or the right), and help establish the size and character of the virtual space. The timing, directionality, and intensity of early reflections depend on room geometry, surface materials, and the position of the sound source and listener.
3. Reverb: Homogenized late reflections comprise the prolonged decay of reverberant sound following the initial onset of reflections. The length of which is measured in RT60 (Reverberation Time 60). Think of RT60 as the amount of time it takes for the reverb to decrease by 60 dB or match the inherent noise floor of the space (whichever comes first). For example, most great concert halls have an RT60 of around 2.4 seconds before the hall is “silent” again. The reverb tail is characterized by a gradual decrease in intensity from the complex interplay of overlapping reflections. The shape, density, and duration of the reverb tail are influenced by factors such as room size, surface materials, and acoustic treatment.The beauty of digital reverbs is that we have the ability to adjust these parameters in ways that simply cannot exist in the physical world. Some plugins like Waves’ TrueVerb ($29 street) will allow you to adjust these parameters to unnatural proportions.“The creative possibilities of reverb can enable you to sculpt some downright captivating soundscapes.”
Now, let’s try to use reverb paired with other effects rather than an end result by itself. Put a short reverb (RT60 of less than 1.5 seconds) on any audio track, then follow it with a reverse delay with a small amount of feedback (around 30 percent) and around 1 to 2 seconds delay time. Hear how the reverb feeds into the reverse delay? Adjust to taste and experiment.
We can also start to modulate the reverb. On an aux bus, place a pitch-shifter like Soundtoys Little AlterBoy ($49 street), set the transpose to +12 semitones (up an octave), and mix to 100 percent wet. Adjust the formant to make it sound even more strange. Follow this with a reverb of your choice, also set to 100 percent wet. Now, route a selected audio track (perhaps a vocal or a lead guitar solo) to the aux bus and adjust your aux send level. Now you have a pitch-shifted reverb to add some octave sparkle.
Next, add in a tempo-synced tremolo or panner after the reverb and enjoy the results! I like doing things this way because you can easily switch the order of any effect and save the effect chain. For added bliss, try applying a high-pass filter to remove low-frequency mud, allowing the reverb to sit more transparently in the mix without clouding the low end.
To hear this in action, I invite you to listen to my new single “Making the Faith” (Rainfeather Records), especially the bridge section of the song along with my guitar solo. Until next time, namaste.

Some of these are deep cuts—get ready for some instrumental bonus tracks and Van Halen III mentions—and some are among the biggest radio hits of their time. Just because their hits, though, doesn’t mean we don’t have more to add to the conversation.
Naturally, every recording Eddie Van Halen ever played on has been pored over by legions of guitar players of all styles. It might seem funny, then, to consider EVH solos that might require more attention. But your 100 Guitarists hosts have their picks of solos that they feel merit a little discussion. Some of these are deep cuts—get ready for some instrumental bonus tracks and Van Halen III mentions—and some are among the biggest radio hits of their time. Just because their hits, though, doesn’t mean we don’t have more to add to the conversation.
We can’t cover everything EVH—Jason has already tried while producing the Runnin’ With the Dweezil podcast. But we cover as much as we can in our longest episode yet. And in the second installment of our current listening segment, we’re talking about new-ish music from Oz Noy and Bill Orcutt.
A dual-channel tube preamp and overdrive pedal inspired by the Top Boost channel of vintage VOX amps.
ROY is designed to deliver sweet, ringing cleans and the "shattered" upper-mid breakup tones without sounding harsh or brittle. It is built around a 12AX7 tube that operates internally at 260VDC, providing natural tube compression and a slightly "spongy" amp-like response.
ROY features two identical channels, each with separate gain and volume controls. This design allows you to switch from clean to overdrive with the press of a footswitch while maintaining control over the volume level. It's like having two separate preamps dialed in for clean and overdrive tones.
Much like the old amplifier, ROY includes a classic dual-band tone stack. This unique EQ features interactive Treble and Bass controls that inversely affect the Mids. Both channels share the EQ section.
Another notable feature of this circuit is the Tone Cut control: a master treble roll-off after the EQ. You can shape your tone using the EQ and then adjust the Tone Cut to reduce harshness in the top end while keeping your core sound.
ROY works well with other pedals and can serve as a clean tube platform at the end of your signal chain. It’s a simple and effective way to add a vintage British voice to any amp or direct rig setup.
ROY offers external channel switching and the option to turn the pedal on/off via a 3.5mm jack. The preamp comes with a wall-mount power supply and a country-specific plug.
Street price is 299 USD. It is available at select retailers and can also be purchased directly from the Tubesteader online store at www.tubesteader.com.

Boss SDE-3 Dual Digital Delay
boss.info
Though my affection for analog echo dwarfs my sentiments for digital delay, I don’t get doctrinaire about it. If the sound works, I’ll use it. Boss digital delays have been instructive in this way to me before: I used a Boss DD-5 in a A/B amp rig with an Echoplex for a long time, blending the slur and stretch of the reverse echo with the hazy, wobbly tape delay. It was delicious, deep, and complex. And the DD-5 still lives here just in case I get the urge to revisit that place.
Tinkering with theSDE-3 Dual Digital Delay suggested a similar, possibly enduring appeal. As an evolution of the Roland SDE-3000rack unit from the 1980s, it’s a texture machine, bubbling with subtle-to-odd triangle LFO modulations and enhanced dual-delay patterns that make tone mazes from dopey-simple melodies. And with the capacity to use it with two amps in stereo or in panning capacity, it can be much more dimensional. But while the SDE-3 will become indispensable to some for its most complex echo textures, its basic voice possesses warmth that lends personality in pedestrian applications too.
Tapping Into the Source
Some interest in the original SDE-3000 is in its association with Eddie Van Halen, who ran two of them in a wet-dry-wet configuration, using different delay rates and modulation to thicken and lend dimension to solos. But while EVH’s de facto endorsement prompted reissues of the effect as far back as the ’90s, part of the appeal was down to the 3000’s intrinsic elegance and simplicity.
In fact, the original rack unit’s features don’t differ much from what you would find on modern, inexpensive stompbox echoes. But the SDE-3000’s simplicity and reliable predictability made it conducive to fast workflow in the studio. Critically, it also avoided the lo-fi and sterility shortcomings that plagued some lesser rivals—an attribute designer Yoshi Ikegami chalks up to analog components elsewhere in the circuit and a fortuitous clock imprecision that lends organic essence to the repeats.
Evolved Echo Animal
Though the SDE-3 traces a line back to the SDE-3000 in sound and function, it is a very evolved riff on a theme. I don’t have an original SDE-3000 on hand for comparison, but it’s easy to hear how the SDE-3 bridges a gap between analog haze and more clinical, surgical digital sounds in the way that made the original famous. Thanks to the hi-cut control, the SDE-3’s voice can be shaped to enhance the angular aspect of the echoes, or blunt sharp edges. There’s also a lot of leeway to toy with varied EQ settings without sacrificing the ample definition in the repeats. That also means you can take advantage of the polyrhythmic effects that are arguably its greatest asset.
“There’s a lot of leeway to toy with varied EQ settings without sacrificing the ample definition in the repeats.”
The SDE-3’s offset control, which generates these polyrhythmic echoes, is its heart. The most practical and familiar echos, like quarter, eighth, and dotted-eighth patterns, are easy to access in the second half of the offset knobs range. In the first half of the knob’s throw, however, the offset delays often clang about at less-regular intervals, producing complex polyrhythms that are also cool multipliers of the modulation and EQ effects. For example, when emphasizing top end in repeats, using aggressive effects mixes and pitch-wobble modulation generates eerie ghost notes that swim through and around patterns, adding rhythmic interest and texture without derailing the drive behind a groove. Even at modest settings, these are great alternatives to more staid, regular subdivision patterns. Many of the coolest sounds tend toward the foggy reverb spectrum. Removing high end, piling on feedback, and adding the woozy, drunken drift from modulation creates fascinating backdrops for slow, sparse chord melodies. Faster modulations throb and swirl like old BBC Radiophonic Workshop sci-fi sound designs.
By themselves, the modulations have their own broad appeal. Chorus tones are rarely the archetypal Roland Jazz Chorus or CE type—tending to be a bit darker and mistier. But they do a nice job suggesting that texture without lapsing into caricature. There are also really cool rotary-speaker-like textures and vibrato sounds that offer alternatives to go-to industry standards.
The Verdict
The SDE-3’s many available sounds and textures would be appealing at $219—even without the stereo and panning connectivity options, a useful hold function, and expression pedal control that opens up additional options. The panning capabilities, in particular, sparked all kinds of thoughts about studio applications. Mastering the SDE-3 takes just a little study—certain polyrhythms can be dramatically reshaped by the interactivity of other controls and you need to take care to achieve identical results twice. But this is a pedal that, by virtue of its relative simplicity and richness and breadth of sounds, exceeds the utility of some similarly priced rivals, all while opening up possibilities well outside the simple echo realm

Guitar: The Green Snake
Reader T. Moody turned this Yamaha Pacifica body into a reptilian rocker.
With a few clicks on Reverb, a reptile-inspired shred machine was born.
With this guitar, I wanted to create a shadowbox-type vibe by adding something you could see inside. I have always loved the Yamaha Pacifica guitars because of the open pickup cavity and the light weight, so I purchased this body off Reverb (I think I am addicted to that website). I also wanted a color that was vivid and bold. The seller had already painted it neon yellow, so when I read in the description, “You can see this body from space,” I immediately clicked the Buy It Now button. I also purchased the neck and pickups off of Reverb.
I have always loved the reverse headstock, simply because nothing says 1987 (the best year in the history of the world) like a reverse headstock. The pickups are both Seymour Duncan—an SH-1N in the neck position and TB-4 in the bridge, both in a very cool lime green color. Right when these pickups got listed, the Buy It Now button once again lit up like the Fourth of July. I am a loyal disciple of Sperzel locking tuners and think Bob Sperzel was a pure genius, so I knew those were going on this project even before I started on it. I also knew that I wanted a Vega-Trem; those units are absolutely amazing.
When the body arrived, I thought it would be cool to do some kind of burst around the yellow so I went with a neon green. It turned out better than I imagined. Next up was the shaping and cutting of the pickguard. I had this crocodile-type, faux-leather material that I glued on the pickguard and then shaped to my liking. I wanted just a single volume control and no tone knob, because, like King Edward (Van Halen) once said, “Your volume is your tone.”

I then shaped and glued the faux-leather material in the cavity. The tuning knobs, volume knob, pickguard, screws, and selector switch were also painted in the lemon-lime paint scheme. I put everything together, installed the pickups, strung it up, set it up, plugged it in, and I was blown away. I think this is the best-playing and -sounding guitar I have ever tried.
The only thing missing was the center piece and strap. The latter was easy because DiMarzio makes their ClipLock in neon green. The center piece was more difficult because originally, I was thinking that some kind of gator-style decoration would be cool. In the end, I went with a green snake, because crocodiles ain’t too flexible—and they’re way too big to fit in a pickup cavity!
The Green Snake’s back is just as striking as the front.
