Keeley Octa Psi
robertkeeley.com
I’d venture that most guitarists instinctively regard fuzz as a brutish, brainless effect (which is funny given how much energy in our community is dedicated to dissecting the nuances and merits of different fuzz types). Keeley’s Octa Psi, however, transcends mere troglodyte status by combining a fundamentally nasty fuzz voice in three switchable variations, and a web of octave and interval tones that transform the Octa Psi into a synthesizer capable of textures ranging from soaring to demented to downright evil.
Crush of the Space Invader
It’s no mistake that the little figure adorning the face of the Octa Psi looks like a sinister cross between a Space Invader and a Cylon. The Octa Psi often evokes the 8-bit, synthy sounds of ’80s arcade games. But the fact that the Octa Psi’s sounds range to cartoonish extremes shouldn’t suggest to a potential user that the Octa Psi is anything less than musical. And the smart, if complex, control layout ensures you can span both extremes with ease.
The Octa Psi is effectively made up of an analog fuzz and a digital octave section. The knobs on the fuzz side are no-brainer stuff: fuzz, master level, and tone. The 3-position toggle, however, expands the potential of those three knobs exponentially. In each mode the fuzz has a cool, snorkel-y, almost filtered essence, with hints of cocked-wah snarl. The punch voice features a bass-heavy profile that’s cloaked in pea-soup fog at the extreme treble-cut/bass-boost ends of the tone control’s range, but crushes like a Tony Iommi-operated wrecking ball in the middle section. The psi mode is even thicker and doomier, though not just heavier in the bass. There’s also more midrange presence that lends extra definition and makes the fuzz feel more explosive under the fingers. The scoop setting, in very relative terms, sounds almost thin compared to the other two. But no voice is exactly short on power here, so perhaps it’s best to call it focused. Each of these modes, which already have heaps of tonal range thanks to the versatile tone knob, can be altered dramatically by the octave section.
Getting a feel for the octave options definitely takes practice. And though intuitive exploration of the possible combinations is rewarding, it’s essential that you do your homework if you want to maximize the pedal’s potential and avoid musical muddles. The Octa Psi’s complexity is largely down to the fact that it gives you much more than just a few octaves up or a few octaves down to work with. First, you can blend in the amount of octave signal. Then there are eight pitch modes available via the rotary switch. Each of these modes shifts in character, depending on whether you select the octave up, octave down, or dual octave setting with the toggle switch. But you can also reshape the tone by pressing and rotating the blend switch, which, depending on where you’ve set the other octave controls, will add octave intervals, like sharp ninths, stacked fourths, and major and minor voicings. Additionally, each of the preset modes will save your settings in dual mode—even after you unplug.
Controlled Chaos
There is another reason the video game correlation implicit in the Octa Psi logo is appropriate: At times, using it can feel like the sky above your moon base is raining laser bombs and you’re being menaced by alien aircraft from all sides. It can be really chaotic, particularly if you’re finding your way by ear rather than consulting the extensive pitch matrix in the manual. Chords are sometimes rendered into atonal glop, and, like any octave fuzz, it’s often easiest to stick with single-note lines.
But for all the mayhem Octa Psi can unleash, finding a clear musical path can be easy and feel like striking gold. Plus, the pedal is, in its way, quite forgiving. It tracks pitch changes well, and rarely collapses on itself—even when executing whole step bends colored by dissonant intervals. You can also use the octave without the fuzz, which yields conventional sounds like pretty faux-12-string, watery chorus tones, and subtle harmonies for clean leads.
The Verdict
The Octa Psi’s power and tonal vocabulary is impressive. You’ll have to be brave or have a very good memory to move between radically different settings on a dimly lit stage. And we didn’t even mention the wealth of “advanced” settings that include volume tilt, pitch ramping, effect order shifts, and more. But the bounty of smooth-to-sick sounds here means the Octa Psi could be a difference-maker in a studio or recording environment when you’re reaching for tone colors and moods that break norms. And though the Octa-Psi could, on the surface, seem nichey, it’s fun to think about the many musical styles and applications where its sounds could find a home—from doomy Sabbathoid chug, to film scores, to glitchy hip-hop hooks, to video-game sound design.

Our Last Call columnist reflects on a big birthday with some thoughts about living one’s best life.
“Life is what happens to you while you’re busy making other plans.” —Allen Saunders (via John Lennon’s “Beautiful Boy”)
By the time this is published, I will be 60 years of age. I’ve been writing this bit of infotainment for nearly 18 years, so it feels like I should have some life lessons to share. Let me preface it by reminding you I’m not particularly wise, nor have I accomplished much. But I have been gigging for 44 years, and I’m still standing, so here are a few tips that might help fellow musicians on the long journey.
Although ageism is the last socially acceptable prejudice, I no longer sweat it. Because music is marketed primarily to kids, I worried I’d be aged out when my hair began transitioning from black to white in my 30s. I’d dyed it Elvis black for nearly two embarrassing decades to extend my imagined expiration date. By 50, the jig was up; I’d have to dye my hair every four minutes to maintain the illusion. That’s when I realized there are two options: grow old or look creepy.
Turns out, all the anxiety and wringing of hands fearing the inevitable was a huge waste of time and bad feelings. Sure, now I wake up every morning feeling like I have been beaten by a bag of doorknobs. And on a long gig, the weight of my guitar is more important than the tone. And my hearing, vision, and stamina are no longer at their peak. But honestly, life is, for the most part, better now.
I definitely am a better musician today than when I was younger. If you put in the time playing, you will inevitably improve. The key is, you have to work to push past what you already know. A lot of players hit their plateau early and never surpass it. They built a tool kit of riffs and tricks that got the job done, started working professionally, and then stopped working to improve beyond that. If you want to get to the next level in anything, you’ll need to get out of your comfort zone. Want to play better? Do something hard you’ve never done, like learning jazz, bluegrass, or metal tunes and practicing them with a metronome.
“The key is, you have to work to push past what you already know..”
Apply the same technique to other parts of your life. Want to feel better? Get off the couch and push your body with regular exercise, even if it’s just walking for 15 minutes. Want to be better off financially? Invest as much as you can, even if it means you will not be able to afford some creature comforts in the present. Or have that super uncomfortable conversation with your boss and ask for a raise. Want a better relationship? Be vulnerable. Nobody has ever improved their life without going through something uncomfortable. Life will pay you back for the work you put into it.
There’s a common fallacy about youth's fearlessness versus the wisdom of age. I was terrified through much of my youth. I was way too concerned about what other people thought about me. I was constantly comparing myself to others. I did not know what I was doing, and I was broke. I was always scheming and planning to improve life, and then was crestfallen when it never went as planned.
Life became much easier when I learned:
• Nobody is thinking about me. (People are generally thinking about themselves.)
• Comparison is the thief of joy.
• Nobody really knows what they are doing. (We are all just trying to figure it out.)
• If you work hard and live simply, the money thing works out.
• Plans lead to a betrayal of expectation. It’s good to have a plan to motivate you to work toward something, but be fluid. Failed plans will lead you to where you are supposed to be.
• Wisdom does not come with age unless you learn something along the way. If you live your entire life with a closed mind, too afraid or too lazy to think, you are missing out.
• Probably the biggest improvement that’s come with age is I’m learning to live in the moment. Most mental health professionals agree that depression often involves ruminating on the past, whereas anxiety is caused by spending a lot of time worrying about the future. But if you can stay in the eternal now, which really is all there is, then you’re living, not worrying.
I realize this reads like a string of cliché maxims, but that doesn’t make them less true. Let me leave you with a few more.
• Forgiveness is the gift you give yourself.
• It’s okay to not be okay. Life will inevitably hurt. Good or bad, this too shall pass.
Everybody has their theory of spirituality. Mine is, if there is a higher power, how we live our life is how God experiences his creation. I want to use up all my tickets and ride every ride at the carnival. If life has a point, the point is to live it. The Titanic sinks; we in the band play on.

While the pedal builders at Sehat Effectors are in the game for their love of the 6-string, they’ve since begun exploring what effects pedals mean to other kinds of instrumentalists.
This time, I’d like to share my perspective as a pedal builder on how our effects pedals—originally crafted with guitarists in mind—are experiencing an exciting evolution in use. Our customer base spans around the globe, and as it turns out, many of them aren’t guitarists. Instead, our pedals are finding their way into the hands of non-guitarist musicians like DJs, synth players, movie sound directors, and even drummers. Yes, a drummer once used one of my fuzz pedals in a drum miking setup—quite an extreme yet bold experiment! This made me wonder: How did such a phenomenon come about?
Most of the pedals I build are fuzz effects and other experimental types, all primarily tested within guitar setups. But then I visited a friend’s studio; he goes by “Balance” onstage. He’s a well-known musician and producer here in Indonesia, and a member of the hip-hop group JHF (Jogja Hip Hop Foundation). Now, here’s the kicker—Balance doesn’t play guitar! Yet, he’s one of my customers, having asked for a fuzz and modulation pedal for his modular synthesizer rig. Initially, I was skeptical when he mentioned his plans. Neither my team nor I are familiar with synthesizers, let alone Eurorack or modular formats. I know guitars and, at best, bass guitar. My colleague has dabbled with effects experimentation, but only within the guitar framework.
So, my visit to his studio was a chance to study and research how guitar effects pedals could be adapted to a fundamentally different instrument ecosystem. The following is an interview I did with Balance to get a deeper understanding of his perspective.
As a modular synthesizer user, aren’t all kinds of sounds already achievable with a synth? Why mix one with guitar effects?
Balance: Some unique sounds, like those from Hologram Effects’ Microcosm or the eccentric pedals from Sehat Effectors, are hard to replicate with just a synth. Also, for sound design, I find it more intuitive to tweak knobs in real-time than rely on a computer—direct knob control feels more human for me.
Are there challenges in integrating guitar pedals with a modular synthesizer setup? After all, their ecosystems are quite different.
Balance: There are indeed significant differences, like jack types, power supplies, and physical format. Modular synthesizers are designed to sit on a table or stand, while guitar pedals are meant for the floor and foot control. However, they share a common thread in the goal of manipulating signals, eventually amplified through a mixing board and amplifier. The workaround is using converters/adapters to bridge the connection.“If you’re a saxophonist who buys a guitar pedal, it’s yours to use however you like.”
Are you the only modular synth user combining them with guitar pedals?
Balance: Actually, I got the idea after seeing other musicians experiment this way. Effects like fuzz or distortion are iconic to guitar but absent in synthesizer sound options. I believe signal manipulation with fuzz or distortion is a universal idea that appeals to musicians creating music, regardless of their instrument.
This brief chat gave me new insight and sparked my curiosity about different frameworks in music-making. While I’m not yet tempted to dive into modular synths myself, I now have a clearer picture of how fuzz and distortion transcend guitar. Imagine a saxophonist at a live show using a pedalboard with a DigiTech Whammy and Boss Metal Zone—absurd, maybe, but why not? If you’re a saxophonist who buys a guitar pedal, it’s yours to use however you like. Because, in the end, all musicians create music based on their inner concerns—whether it’s about romance, friendship, political situations, war, or anger. Eventually, they will explore how best to express those concerns from many angles, and of course, “sound” and “tone” are fundamental aspects of the music itself. Good thing my partner and I named our company Sehat Effectors and not Sehat Guitar Works. Haha!
