The Darcadiator is a transistor based (discrete) synthy 8-bit sounding square wave fuzz that can do octave down, pulse width modulation and alternating octaves or stutter.

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

This kit is a creation by in cooperation with If you have any problem with the content of the kits like mising or wrong parts, please contact Musikding (Klaus) at For any technical problem relating to building this project, please contact Fredrik at

Pcb de qualité, montage facile, kit bien pensé niveau conception.
Le son est fuzzy, presque synthétique,, pas souffle, reste maintenant à maîtriser la bête.

3 from 5 Very very fiddly circuit

I could never get it to work like the videos. After a lot of fiddling and replacing Q7 with a 2N7000 (backwards) I got something a bit like the octave going, but its unstable and only tend to work on some notes. I had to replace some of the transistors to get anything not muffled on the output. Even then, a lot of cracking now and then and generally unpredictable behaviour.

Ive of course re-checked and reflowed all solders, and verified a bunch of other things. Its been my most painful and unsatisfactory pedal build so far. Hopefully its a one off...
