Oh, and D1 is a 1N5817 or similar for power protection.

Jon Patton's Clipper Ship
Jon has contributed a lot to the DIY pedal building community and I always learn something new when I layout one of his circuits. So I think we'll have a Jon Patton week, starting with the Clipper Ship. There's a good bit of flexibility with this one. Q1 can be pretty much any low gain transistor, germanium or silicon. If you're using a germanium transistor, use a germanium diode for D2 (if you're using a silicon transistor, omit D2). For D3-4 use anything with a low clipping threshold–1N60, 1N34, BAT41, etc. Q2-3 form a cascaded JFET stage (much like the AMZ Mini-Booster and a ton of other designs). Way more info on the circuit can be found here, including the schematic. I've laid it out for a typical 1590B with board mounted pots.
He is my hero <3
ReplyDeleteSnow Day OD, Bearhug and Hamlet is my favourite :D
Jon, Rick Holt, Russ, and You, David = the real perf wizard :D
Thanks for inspire us.
Aww, thanks man! An honor to be mentioned in the same sentence as those dudes. :)
DeleteHey brood! This is a very cool effects box! Even steeper it sounds with any booster))) while the device retains its readability)))) Good luck with the assembly. )))
ReplyDeleteVerified. So many options to mod it...
ReplyDeleteThe 100 nF cap between Q1 and Q2 is not necessary, if you jumper it the sound will be similar. Slightly more bass and crisp.
DeleteCool. Thanks for verifying!
