Here you’ll find a collection of things that I do, make, say, and think. It collects projects published across my sites, including custom-built guitar and hi-fi amplifiers and effects, custom PC servers, and rescued or upcycled hardware. Simply a central place to collect what I’m doing with some of my creative energy at any given time.

Pedal Progression: 2 Suhr Riot
This is another one pulled out of the drawers: an “amp in a box,” a decent rock box at least 15 years ago and still today. Horrid drilling, OK soldering, missing pots, a broken diode, and various parts to replace — ceramics to start.
For this, I am going with the mods suggested in the version “uproar” by mad bean pedals dot com presence, mid boost and 3 options for the clipping. Saving an old box like this there is lots to do, the pcb already had a few fixes for broken traces.
I actually found an old copy of the decal I originally used, so that’ll go on there, and with some cleaning and clearcoat the box wasn’t half bad.
The case is a 1590G, less common, and giving some more space for the pcb size however they are very slim so it can be a struggle with jack’s and switches. However somehow it did fit once all were done.
Given the decal survived 15years in various drawers I’m OK with it having some blemishes. A good thing it’s all fitted together, and it does work while quite a bit more sturdy compared from what it once was. A “nice to have pedal” chaining gain sections or quickly having another dirt option separated from amp gain.
