The permanent kit's smaller clear case, closed, seen from above. A lime green label on the lid reads Onion Madder's, Breadboard Kit, Bazz Fuss, messopedals.com, beside a black outlined heart with a pulse line through it. Below the label the folded bench guide shows through the plastic.

Permanent breadboard kit · One transistor fuzz

Bazz Fuss

DIY Kit

Christian Holmberg's fuzz, about the smallest real one there is: one transistor, one diode, one resistor, two capacitors. Rude, gated and synthy on the decay, where notes collapse rather than fade. This is the one you plug a guitar into.

Read the build first

The whole build is free on the Bazz Fuss guide: the parts list, every hole, how it works, the mods and the troubleshooting table. The bench guide in the box is the short version for the bench, with a QR code back to the full one. If you already have the parts, you do not need the kit.
