- Tone Machine™ Ready-For-Transfer Printed Circuit Board Layout – For use only if you are a complete DIY person who wants to etch and drill your own PCB. Otherwise, we recommend you ignore this PCB mask and buy the Ready-to-Solder Printed Circuit Board or Complete Kit.
Buy a FTM Complete Kit. Includes all the parts and materials you need to build one, all for about the price you would pay for a PCB and parts.
Would you like a Ready to Solder Circuit Board for this project? Note: If you buy the kit, the Ready-to-Solder Printed Circuit Board (RTS PCB) is included in the kit. You do not need to purchase this Ready to Solder Circuit Printed Board if you buy the kit.
This is one of my favorite of the old-time fuzz tones (1965-1975 era). I love the long sustain capabilities. I used the “Tone Machine” section from my original fOXX Fuzz/Wah/Volume pedal as a guide for building this one (sound comparison). The circuit is the same as the Tone Machine. The original has orange drop caps and other large size film caps for the non-electrolytic caps.
I tried lots of different transistors, 2N2222A, 2N3904, PN3565 and 2N5088. I could not hear any difference in the sound with any of these different transistors. My original has BC237B transistors. If you want to use sockets on the transistors, the layout is designed to use SIP sockets for the transistor sockets.
