The Theremin Fuzz is a guitar effect that produces a sound similar to a real theremin instrument, but controlled with the input from your guitar.

This circuit works best with high output pickups. It is a gated circuit by nature of COMS technology If you are using single coils and need more sustain, try a boost or compressor in front. To tighten up the octave tracking, use your neck pickup with the tone rolled off.

4 from 5 A little tricky, but doable.

came with small led, but case was drilled for large led... came with extra pcb for easier switch/led wiring... I also bought the bit-crusher, and with both of these kits, I miss easier instructions. Its do-able and not impossible, but it couldve been done smarter.

5 from 5 Easy build

well laid out, super easy build. Sounds great. It is what it claims to be and I expected nothing more.

4 from 5 Interesting effect and easy to build.

Pcb board very fine made, components are also good quality. Finished all pedal in 3 hours.
Hole in enclosure wider than 3mm led with plastic bezel.
Sound of the pedal interesting for experimenting. With delay and reverb inspiring to create very crazy melody lines or improvise for solos of own songs.
For me that pedal is not FX Nº1, but definetly it can be useful to have in arsenal of the pedals.

5 from 5 Fun build, easy if you are steady and precise

I use a thin point on my iron and taking your time while being precise will go a long way. Very satisfied with the results, always wanted a pedal that could give me a Reeves Gabrels “Searching for Satellites” Theremin effect. I will definitely order more of these in the future, I know a lot of my customers will want one once they see mine.

5 from 5 Fun and good

Happy with the quality of the kit. Fun build for an effects box somewhat outside the classical standards, with weird sounds one has to tame.
