OLD AND/OR DISCONTINUED PROJECTS AND LIMITED EDITIONS

0415 GUITAR SYNTH (discontinued)

The 0415 Guitar Synth was an attempt to design a very minimalistic PLL based guitar synth with a decent tracking and not just pure chaos and noise like the Raygun Youth fuzz. This basic circuit that later evolved into the Into the Unknown.

 

I plan on updating this circuit to make it even better, and use a different IC instead of the CD4015, so for now this DIY project is discontinued, but you can still build the stripboard version.

Here's a small silly "demo song" I recorded with the 0415 Guitar Synth pedal.

APRIL 77 Fuzz and ROOM 1015 Distortion

Two Limited Edition pedals that was made in cooperation with two french brands.

 

I love to do odd collaborations like this. If you have an idea for a small batch of pedals, please contact me. :)

The April 77 fuzz

It was made for their store in Paris in 2014. It's my own original design, a circuit called the Flying Guillotine Fuzz, but with a few small modifications. The batch was build on etched circuit boards with a laser engraved enclosure. It was sold together with a exclusive leather pouch.

The Cherry Punk distortion

It was made for the new Cherry punk perfume released in 2020 in matching red. This pedal was a clone of a Sonic Distortion. I didn't want to put the Parasit Studio name on this pedal as it wasn't an original design and far from what I normally do.

Prototype
A small army of BitBreakers

BITBREAKER DELUXE (discontinued)

The BitBreaker Deluxe is a small Attiny85 based square wave fuzz with octave down (4 different octave settings) in a small 1590A enclosure.

 

It was sold as a fully assembled pedal back in 2018, and has never been available as a DIY project with a finished PCB. However, both a stripboard layout and a hex file is available here for anyone that wants to build it. But you need to program/upload the hex code to the Attiny85 yourself.

 

I kinda hate building pedals in the 1590A format haha, so I stopped building this one. But if anyone really wants one, get it thouch and I will think about building more of them. :)

BLACK CURRENT TREMOLO

The Black Current tremolo was one of my first original designs from 2014 - an agressive tremolo / stutter pedal with minimal controls.

This one was never made into a PCB. Maybe I should make it into a PCB? Let me know if you would be interested. :)

The idea is simple: the signal is split into two paths that are out of phase. One side is goes though a highpass filter (that cuts eveything below about 500hz) and amplitude modulation, then both signals are summed back together. As the two signalpaths partly cancel out from 500hz and up, this creates an interesting phasey sound in the crossover frequencies - a vibrato'ish sound that is a bit different from your standard tremolo.

 

The newer Green Currant tremolo (available as a DIY project) is working in a similar fashion, but doesn't require any JFET.

There are some questionable design choices in this circuit. Build it at your own risk...

 

BLIPBLOP RANDOM NOTE NOISEMAKER

Here is a silly litte noisemaker that I designed back in 2014 when I was bored of making regular guitar effects. The Atari punk console didn't do it for me, so I came up with the random note generator based on a LM13700 VCO. The LFO is based on R.G. Keens pseudo random LFO.

If I was to redesign this one, I would probably use a CD4046 instead for the VCO, as that would require alot less parts.

 

This little project had never been made into a PCB. Maybe I should have? :)

DOGBOY DISTORTION

The dogboy Distortion was my first attempt at creating a heavey/crunchy distortion/fuzz. It sounds a bit broken, in a good way.

 

Looking at the schematic now I wonder what I was thinking putting the transistor inside the feedback loop of the opamp, with a capacitor in reverse. Eeeehhh?!...

 

Built this one at your own risk. :)

Sound example

FLASH FILTER FUZZ (discontinued)

The Flash Filter Fuzz is an inverter-based squarewave fuzz with a resonant highpass filter and sample & hold modulation. I made layouts for two different versions, a light version (without the s&h modulation) and "deluxe" version.
 

THE FLAWED LOGIC FUZZ (discontinued)

The Flawed Logic Fuzz is a square wave fuzz with a NAND gate oscillator that creates a mangled resonant sound. It was available as a PCB for a short while, but for some reason I can't remember now I chose to discontinue it. Maybe it needs a comeback?

 

The mark 2 version added a triangle wave to the LFO, a depth control and better sustain.

FLYING GUILLOTINE FUZZ

The Flying Guillotine fuzz was one of my earlies pedal creations. It borrowed the front end, tone stack and the output stage from the Big Muff, but the two Muff gain stages are replaced with a discrete op amp by Joe Davisson. This design was never made into a PCB.

Named after one of my favourite movies

Sound example

KING CORRUPTOR

The King Corruptor took the original Corruptor pedal and added a step sequencer to the ring modulator oscillator.

8 different steps that can be configured in alot of different ways. It can also be used as a stand-alone sequencer "synth" or a square wave fuzz and it can also do regular ringmod sounds. I tried doing a PCB layout for this project, but had some trouble getting it right so I abandoned it.

LM311 FUZZ

Here is something that is mostly just proof of concept. I was playing around with Craig Anderton's Comparator Fuzz, but I wanted to try a dedicated comparator IC insted of an op amp. It's a very gated fuzz (all comparator fuzzes are). A good idea would be to put a booster in front with a volume pot to control the sustain and make it more friendly to low output pickups. This was never made into a PCB.

Sound example

PARASITE PHASER

A PWM based phaser that uses a CMOS switch as variable resistors. The main advantage to this approach is that you don't need to match JFET transistors or LDR/Vactrols.

 

Here's another project that I tried turning into a PCB, but it had some noise issues so it was never released. I might return to this project in the future and add some fun twist to it, like more LFO waveshapes.

STEPPING STONE OVERDRIVE

This was my first attempt at making my own overdrive from what I had learnt by building and modding other circuits. I had done a few heavily modded ones before, but nothing really original. I spent countless hours trying out different ideas on the breadboard before I was satisfied with the result. However, going back listening to this one now I find it alittle too thin/midrangy sounding.

Sound example

SILVER FOX OCTAVER

The Silver Fox octaver was one of my earlies CMOS based designes. It uses a gated oscillator to produce a pseudo octave down, similar to the Tofuzz (below) and the Sidescroller (MK1). It's a bit weird and unruly compared to a typical flipflop based octave down circuit.

Named after the kung fu movie actor Hwang Jang Lee that mostly played a badass villain.

TOFUZZ

The Tofuzz (named after my favourite food) is an odd opamp based fuzz configured as a comparator and gated oscillator that creates a pseudo octave down effect on certain frets on the guitar.

 

Get your chop(sticks) ready!
