Runoffgroove UBE Screamer
Another interesting circuit design by ROG; using a hex invrter to emulate a Tubescreamer Schematic and a writeup is avaiable HERE. Note that the resistor labelled “X” in the schematic is replaced by a 500k trimpot so you dial in the right amount of clean signal. Set it at around 100k for single coils, 220k … Read more
Runoffgroove Omega
Quite an interesting little treble booster from ROG for Vox toanz. Schematic and a writeup is avaiable HERE.

Runoffgroove 22/7
A DIY classic by Runofgroove. It is a Big Muff but the transistors is replaced with hex inverters. Schematic and more info HERE.
RUNOFFGROOVE: Supreaux Deux
The follow-up on the Runoffgroove Supreaux, the Supreaux Deux. An improved version of the original Supreaux design, running at 18v and with some changes to match the sound of the original amp as closely as possible. Please follow the link to the runoff groove site, as there’s an amazing amount of info on the development of … Read more
RUNOFFGROOVE: Supreaux
This is the Runoff Groove Supreaux, their first interpretation of a Supro 16T amp. It’s also known as the JHS Superbolt – which is almost identical to the Supreaux, but runs at 18v with a gain switch added. Just put the schematics side by side, and you will see what I mean. I added … Read more
