D’oh! I omitted a circuit from the Fuzz Detective video. It’s the germanium version of the Shin-Ei Companion Fuzz FY-2. So here’s a brief Fuzz Detective Appendix.
The silicon version of the FY-2 is a cult item, a nasty little thing best known for its appearance on Jesus and Mary Chain’s Psychocandy album. The germanium version (which I didn’t even know existed until reader Bear pointed it out!) is a very different beast. Most notably, it lacks the silicon version’s signature midrange scoop, delivering a thicker, fatter sound.
As noted in the video, I replaced the stock B50K gain pot with a B5K. (The overall range of tones is pretty much the same, but this way, all the variations aren’t crammed into 10% of the knob’s range.) Construction details and testing procedures are the same as they were for the 12 Fuzz Detective pedals. (more…)
Man, I’m glad I announced my intentions about this project! Thanks to your links and suggestions, the “Fuzz Detective” project has grown vastly more ambitious. I need a few more days to make my test recordings are assemble the results, but I believe this will be the most complete and “scientific” audio comparison of 1960s fuzz circuits yet attempted. I’m posting this update to share my current plans — and solicit last-minute suggestions for improving them. —Joe
Wanker’s dozen: twelve germanium fuzz pedals will finally compete on a level playing field.
I’ve been a busy little solder monkey! Dig my new pedals:
1. Maestro Fuzz Tone FZ-1 clone
2. Sola Tone Bender “Mk I” clone
3. Sola Tone Bender “Mk 1.5” clone (near-twins: Vox Distortion Booster, Italian Vox Tone Benders)
4. Dallas-Arbiter Fuzz Face clone (very similar to Tone Bender Mk 1.5)
5. Hornby-Skewes Zonk Machine clone (near-twin: Tone Bender Mk 1)
6. Sola Tone Bender “Mk II” clone (near-twin: Marshall Supafuzz)
7. Orpheum Fuzz clone
8. WEM Pep Box Rush clone
9. Mosrite Fuzzrite clone (germanium version)
10. Selmer Buzz-Tone clone
11. Sola Tone Bender Mk III (“3-knob”) clone
12. Baldwin-Burns Buzzaround clone
About the Fuzz Detective project:
I’m attempting to create a comprehensive comparative sound library of germanium-transistor fuzz pedal circuits.
There’s no shortage of audio clips and demo videos featuring the great stompboxes of the ’60s and their modern clones. Yet it’s difficult to make qualitative comparisons between circuits because there are so many other variables at play. Who performed the examples? Using what gear? Were the examples recorded in a pro studio or on a mobile phone? Are the pedals ’60s originals or modern clones? What’s the condition of the transistors? And so on.
This isn’t about, say, deciding who makes the best Fuzz Face clone. The focus is the circuits themselves. The Fuzz Detective project aims to “level the playing field” by removing as many variables as possible. (more…)
