Jon Pattons Cruz’ Driver

About the circuit Jon Patton is a great engineer in building guitar effects. He developed a good number of circuits that are well known in the DIY community. What Jon sais about this circuit: This was a fun challenge, and it came together pretty quickly once we identified what would work well with his amp […]

OD 67 Overdrive – DIY

This is based on a DOD 250™/ MXR Dist+  overdrive which is a straight-to-the point distortion unit. In addition to that Brian Wampler has written a nice article in premierguitars which discussed a lot of modifications to optimize the circuit http://www.premierguitar.com/articles/mxr-distortion-plus-mods-1 Those mods are switchable on the OD67 board. The most usefull one (which the […]

ROG Azabache – DIY

This is my PCB for runoffgroove’s Azabache overdrive. Here is the link to ROGs project and their soundfiles. The Azabache is a Fender-like overdrive covering a lot of their models because of the special tonestack and switching used. Board mounted pots can be used to make the build easier. For reference: (out of production)

OD 66 – DIY

The OD 66 Overdrive is based on the old DOD 250(TM) Overdrive. This version features an additional switch for the selection of different clipping diodes. This build is easy for beginners and fits a 1590B enclosure easily.   The V1.1 version features the 9mm helper pot, better aligned Pads and an on-board switch. The OD-66 […]

ROG Supreaux-Deux V1.1/1.3 – DIY

This is my PCB for runoffgroove’s Supreaux-Deux overdrive. Here is the link to ROGs project and their soundfiles. The Supreaux Deux is moddeled after a single ended SUPRO 16T. Board mounted pots can be used to make the build easier. V1.3 has a smaller layout and testpoints added to make biasing the JFETs easier. Older […]

ROG Umble V1.0/1.2/1.3/1.4 – DIY

This is my PCB for runoffgroove’s Umble overdrive. The circuit has been altered to have less gain. The original had way too much for my liking. Listen to the soundfiles! Here is the link to ROGs project and their soundfiles. The Umble is modelled after one of the famous Dumble amps. Board mounted pots can […]
