I use it for my bass. It has just two knobs, it’s simple, and sounds incredible!! If you play in a band that leaves a little room for the bass player to take a solo every now and again, just flip this on and have a blast.

If you're looking at this pedal you probably already know about Ezhi & Aka. This pedal isn't for everyone, but it's for me and those of like minds. The people who like to communicate with spirits. Do those communications always make sense? No, but you keep speaking and you keep listening, and you keep hearing insights that can come about no other way. This one is for the adventurous curators of found sounds. Those who like to play in other worlds and get lost in abstract communications.

Excellent pedal. Fantastic built quality. The smoothest knobs on any pedal I have ever owned.
Sonically, there is a lot to explore. The slightest change of knob position leads to new textures and harmonics. Hours of tinkering. It's a little lowfi with a moderate/high noise floor, but for most music you would put this pedal with - that does not matter at all.
I'd be keen to see a V2 at some point with expression control over knobs because that's where I think the true creative joy lies.

Truly a feat in tech, the polyphrase is incredible at performing long delays that goes into looping. The modulation can go from gentle to transformative through some really creative waveforms of vibrato.

I have an embarrassing number of fuzz pedals. It takes a lot to justify adding another to all the Tone Benders, Fuzz Faces, Big Muffs, octave fuzzes, wave rectifiers…you get it. But this OC201 is really something different, and aligns with my burgeoning love of preamp-type pedals. It sounds awesome, especially how you can crank the gain and still maintain a ton of clarity, even with chords and rhythm. Killer!

Unit works as described. It’s very very small so fitting it under a pedalboard was very easy.

When I first turned it on I was suprised by how much it smoothed out my signal chain. Flipping the toggle switches on the bottom provided an excellent boost in volume. It’s very intuitive and easy to use with each knob helping shape the overall sound. My favorite pedal that I own so far. I would highly recommend it

This delay is my perfect one. Simple done well seems to apply to everything in life, this is like the Cacio e Pepe of delay pedals.

Another fantastic pedal from Ezhi & Aka…if broken soundscapes and “sentient artifacts” are your thing, this is the pedal for you. Excellent for ambient—also the fuzz is incredible.

I use this alongside a Chase Bliss Mood to make loops out of material that later gets tracked in songs. The Tensor does meat and potatoes styled looping with a few nice tricks up it's sleave. I'm able to get predictable results out of the loops (which is good). The Mood, i get less predictable results, but sometimes great art. The Tensor does the basics really well. My only complaint is that when I shift the time knob left to slow down the loop, it starts to loose its fidelity and sound a little crunchy and grainy. I'm not sure why that is. Time doesn't change the pitch, it just slows down playback time. I wish it kept the clarity.

This is yet another fantastic offering from Empty Head Effects and would find a home in just about any set up! Stacks incredibly well and is also a fantastic standalone overdrive. Very flexible sound options on tap. You’ll love it!

Ezhi pedals have become somewhat legendary over the years and the Brom fuzz is just another beautifully nasty addition to the roster. There are a plethora of schizoid sounds that you can summon from this thing and its tone is massive. The 4 knobs and two (3 position) switches offer an endless combination of fuzz flavors and textures. Definitely for those who love experimentation and are willing to let the pedal guide your playing.

I wanted a CMOS type of drive sound without the investment in a B3K which is basically what the FTelettronica CRITICAL THEORY is. It's not a tone I need often but is something I wanted in my arsenal. I've never used a B3K pedal but do own some amps with the Microtubes and Alpha-Omega circuits. I'd say this does an excellent job. My only quibbles are related to the arrangement of the controls. I don't understand why the graphics are arranged horizontally rather then vertically. I would've arranged the controls more like the B3K. The switching order is peculiar. For the Treble toggle, it's arranged logically, bottom/cut, middle/flat and top/boost. OCD Note: the word, CUT, is upside down from all of the other words in the arc. For the Bass toggle, the order is changed to down/boost, middle/cut and top/flat. The B3K is also not logically set up in regards to the toggles with the Treble being down/cut, middle/boost and top/flat and the Bass being down/flat, middle/cut and top/boost. Neither pedal is consistent. I'm not into heavy distortion. I have 2 favored settings with this pedal. One has the Drive at 12:00, the Blend at 6:00 and the Level to unity which, for me, has it aimed at the LED. The other variation I like changes both the Drive and Blend to 9:00. In both cases, I set the toggles to boost the bass with the highs kept flat. The pedal seems solidly made.

If you want predictable sounds, this one is not for you. If you like to explore and stumble upon sounds you’ve never heard before, this is for you. If you need presets, they are not here. If you need tap tempo and/or envelope control, this has it.

Outside of the great job that it does as a lofi, dark, vibrato pedal, this pedal also exceeds at being a 2 in 1 compressor and chorus in one switch. I set this up in front of a dirty amp and set the pedal volume low so it cleans up before the amp and simultaneously adds chorus. I can't think of any other pedals that do this, and the instant lofi junky nails it!
