COLORSOUND™ TONEBENDER™ MARK II REPLICA COMPLETE KIT

A complete kit for a replica of the Colorsound™ Tonebender™ Mark II Professional, built as a great-sounding NPN silicon fuzz, with transistor sockets so you can drop in germanium transistors if you prefer.

About the effect

The Tonebender™ Mark II is a classic 1960s British three-transistor fuzz, also sold as the Sola Sound Tonebender™ and possibly the Vox™ Tonebender™, with small part-value differences between brands. GGG recommends the silicon version as a simple and great-sounding Tonebender™. The project page documents four versions on the same PCB and wiring diagram: NPN silicon, PNP germanium, NPN germanium, and PNP germanium with a charge pump so it can share power with negative-ground pedals.

What you get

The kit contains all the parts to build the NPN silicon version, including the PCB and transistor sockets. It includes all the parts for any of the versions on the project page except the germanium transistors themselves; for a germanium build, get your own (Small Bear carries them) and plug them into the sockets. Enclosure options:

• 125B: spec sheet.
• 1590B: smaller; spec sheet.
• No Enclosure: everything except the enclosure.
