Parentheses Fuzz

What GE diodes are best for D1 and D2 in this build?

I haven't built this yet but from my research I plan on using matched 1N5817s in mine. I also probably will socket these

I’ll 2nd @xconverge - I’ve built at least 5 pedals with that Tentacle circuit in it, and matched 1N5817s have been my favorite so far.

yes hello it is me, the research. Use 5817s.

For what its worth Ive done 5817’s matched and d9e’s matched. Both gave a good octave effect. Id do the 5817’s based on they are cheap and save the germs for clipping

im gonna be the contrarian and say that I wasn't all that impressed with matched 5817s when i breadboarded the octave circuit (numerous times).
not trying to be a dick, it's just that i got better results with matched D9Es (but tbh i can't remember how much attention i was paying to leakage values).
regardless, 5817s do work just fine.

also gonna throw my 2 cents in and suggest it's not only the diodes that need to match.
- if you really give a shit about having a nice strong octave effect, i've found it also helps to match C4+C5 & R11+R12

that too^, I always match all the resistors and caps around the diodes (R13/14 too)

yeah ive always done R13+R14 as well, moreso out of habit/fixation, but on reflection i'm not sure it matters as much cos it's just a voltage divider/voltage ref point.

turn down for what

Since it's not just clipping, but rectum-frying, matching all components can help ensure the folded over (lower)wave is of close level to the original waveform(upper).
If you really want to tune it, install the JDSleep trimmer and tune it with a some wave and scope

Thank you all for the suggestions and help I appreciate it.
