AnalogMan Sunface

 Happy Fuzz Friday! Been meaning to redo this one for a while with board mounted pots. A buddy of mine was reminiscing about a Sunface he used to own and wish he still had, so I built this with some OC71s for his 40th b-day. AnalogMan has used loads of different transistors in these over the years, both germanium and silicon, so socket and experiment. Easy fit in a 1590B.

AnalogMan Prince of Tone

Wanted to redo my old layout with board mounted pots. I've laid it out with the Presence control externally and the diodes on a DIP switch, though you could easily wire up an external toggle if you want. Should fit nicely in a 1590B. If you want the King of Tone, just but 2 in one box.

Analogman King of Tone

Here's Analogman's original version of the King of Tone, a highly regarded overdrive with a few "unobtanium" diodes. It's probably best to socket said diodes to play around with your favorite combinations. Switch A controls the 4-diode array in the feedback loop (much like a Tube Screamer), while Switch B controls shunted diodes (much like a RAT or Distortion +). Originally these were DIP switches, but it makes more sense to me to have these externally.

Analogman Sunface

The Sunface is a clone of the Dallas Arbiter Fuzz Face, with a few tweaks. First, it has a 50k trimmer at the input of the circuit so you can adjust the pregain (it works exactly like the volume pot on your guitar), second it has an external control for biasing Q2 (the Sundial). Original units use a B5k pot here, which in series with the 2.2k resistor doesn't even equal the original Fuzz Face bias resistor of 8.2k. So you might want to up that pot to a B10k.

Analogman has made both a positive ground, germanium version, and a negative ground silicon version. The germanium versions have NKT275 transistors, and the silicon version uses the BC108. The layout reflects both versions with the perf side showing positive ground, and the PCB side showing negative ground.
