Distortastudio Cassette 4-Track Colour


  • Full Kit
  • Step-by-Step Guide
  • Supported
  • Beginner

Do you ever pine for the cheap and dirty, but somehow musical and inspiring, sound of your old portable 4-track? The Distortastudio brings that sound to your Colour Palette without a big tape machine taking up space in your studio.

The Distortastudio's circuitry is directly inspired by the channel strip of a late-80's TASCAM machine. It even features the same opamps, obtained NOS (new old stock) and available in a limited quantity.

Just like your old 4-track, you can run the Distortastudio at low gain for subtle solid-state dirt or at high gain for trashy distortion and hiss.


  • Four stages of channel strip circuitry
  • Original, NOS opamps
  • Compatible with the Colour format
  • Black PCB
  • Full, step-by-step assembly instructions

Real analog plugins.

Colour is a new format for analog audio gear designed for and by the DIY community. We took our favorite sounding analog circuits and put them on modules that are small, affordable, and swappable.

The Colour format consists of Colours and Palettes:

Colours are ultra-compact, pluggable analog circuit blocks that impart various types of analog color. Check out our ever-growing selection of Colours. Colours can be designed and released by anyone.

Palettes provide controls, power, and support circuitry for Colours. We currently offer the Colour 500 Palette and CP5 Mic Preamp with Colour.

Dirt, crunchy, gritty sound

When you need to dirty something up, this is the move. I bought this to add some real dirt and crunch to my colour palette chain. I’ve been slamming my bass guitar through it to get super crunchy warm tones. As a music producer primarily using the computer, i’m always looking for ways to dirty up sounds that suffer from being too digital clean/plastic-y. This thing is a nice cure all for that “i recorded this demo in my bedroom in the 1980s sound.” As always, super super fun to build, really easy and intuitive instructions. An absolute blast for a super audio nerd like me.

Awesome raw, dist, sound. Get some drums thru it, trust me it wont disappoint!

Great for crapping up a track

While my title doesn't necessarily sound like a compliment, it is. It really helps get the fuzzies in there and is a blast on drums or bass. Fairly easy to build, so a definite thumbs up. If you have played with guitar, you know how annoying dirt boxes can be. They just are never quite right. This is different, it makes that dirty sound the way it sounds in my noggin, so that was great for me. Great price as well.

Simple build - nice colouring

It took 10 minutes to build each kit and I dig the sound of it. Useful on different sources!

Soldering fun!

Another fun little project for an afternoon! Looking forward to using my Colour Pallette(s) and CP5s on a recording project!
