HGE Contraptions Relay Bypass Pedal (162nd pedal built)
Just finished a Relay Bypass pedal for my Ceriatone Chupacabra 50 effects loop.
Very simple design, but efficient.

Fixed a deluxe bass Big Muff pedal
Fixed a deluxe bass Big Muff belonging to a friend of a friend (he sent me some pedals to test for fun and he included this faulty unit). Works now.

Mods for my Yamaha HS-8 Monitors
Swapped the NJM4558 IC-s in every monitor with OPA1602 IC-s and also removed the limiter circuit.
Now, they don't push exaggerated mids that much, and are a little flatter. A little better for accurate mixing and monitoring.

HGE Contraptions 2nd Resistive Attenuator Build (161st "pedal" built)
Yesterday I've finished the second attenuator clone of my first clone 🤣 (SPL Reducer).
Absolutely useful, even if only resistive, and didn't have to pay 800+ euro for the originals new 🫠😱
Now I can have my stereo setup with an attenuator per amp/w. two cabs each.
Random video test with a Crate Blue Voodoo modded:
