Proco – RAT – Clone

Next, I took the original RAT from ProCo. I used the circuit from TonePad: tonepad_rat.pdf. I replaced the specified JFET transistor 2N5458 with a 2N5457, as the 2N5458 I had from China was probably a fake. Fortunately I got my money back. I now understand why ProCon called this effect pedal Rat.   I then…

MXR Distortion + Clone

I’m in the process of trying out some classic distortions and just building them myself. That’s what I did with the MXR Distortion +. The board is quite small and fits very well in the 1590B housing. I got the design from http://tonepad.com/project.asp?id=2 and have used “Mas Distortion, Rev.4.Dec.8.2005”.

GreerAmps – Ghetto Stomp – Clone

I gave a friend a self-made Nano Big Muff Pi for his 50th birthday. Unfortunately, he only enjoyed it for one day. When the battery ran out, he connected a power supply with the wrong polarity. So I thought I’d better make him a distortion unit that was a bit simpler. In my search I…

Unimod – A Versatile Sound Effect Generator

I found this project in the US magazine Popular Electronics, February 1981. Here is the link to the document: Unimod-Sound-Effects-Generator.pdf. I was interested in how this effect sounds and after finishing it, I can only say it sounds interesting. The assembly takes place in a simple TEKO housing. I changed the circuit board a bit,…

Electro Harmonix – Big Muff

A distortion device is also a fine thing, I thought to myself, and made one for myself. A Big Muff clone from Electro Harmonix. There are many different templates on the net. I decided me for one of http://tagboardeffects.blogspot.com.   I used a simple TEKO case and glued it with hot glue. The distortion is…

Electro-Harmonix – Big Muff π clone

In another post I reported that I have built a Big Muff clone. Now I have again built a version, but this time in an aluminum housing as a floor pedal.I have ordered a board and a few other parts, as well as an aluminum housing from https://www.musikding.de/. I printed the front panel on a…

Electro Harmonix ‘Bad Stone’ Clone

This time I made a Bad Stone Phaser. I used an aluminum case for a floor pedal. The PCB and some other parts I ordered at https://www.musikding.de/. I printed the front panel on a transparent foil and took the design from Electro-Harmonix. In contrast to many other phasers, this one is much easier to set…
