Joyo Vintage Overdrive D1 and D2 Diodes Value?

[alex73013]

I ordered some 1n34a germanium diodes through guitarparts.com to replace the stock diodes in D1 and D2 of my Joyo Vintage Overdrive Pedal. I wanted asymmetrical clipping so the plan was to wire two germanium diodes in series in the D1 spot. When I opened the pedal up the stock diodes in D1 and D2 looked identical to the germanium I had gotten so I just wired two new ones in series to replace the D1. The Joyo now sounds a little meaner but not far off from the stock version. I forgot to take a picture of the end result but this picture is of the stock format.

Can anyone confirm the stock diodes value?

Those aren't Germanium diodes. Those are Schottky diodes (probably 1N60P). It's a common bait and switch, especially for 1n34A's. I believe those Schottky diodes are the modern day replacements for the 1N34A germaniums. I've even seen them marked as 1N34A. They'll probably work in place of a 1N34A germanium in most cases, except for crystal radios. But that doesn't mean they sound the same as clippers (they generally don't). Worse, there are even some diodes that actually look like germaniums that aren't germaniums. Or, the photo will show a real 1N34A germanium and what you received will be those 1N60P Schottky's.

At any rate, if you want to be sure that you will be getting real germanium diodes, go to smallbearelectronics.com ... They probably wont have an 1N34a's but get a few 1N270's or some of the Russian D9* types. The 1N270 is usually close to the same forward voltage drop as the 1N34A. You'll pay around 75 cents each for the 1N270's but they will be the real thing. How much difference it will make, I don't know. It will depend on the circuit.

Thanks for the reply. I probably won’t mess with getting new diodes because I really like what’s going on with it now.

Not to heist the OP's thread but do you know where to get pots that look like the ones on his Joyos PCB ? I need a 50K 10mm shaft,with B503 on the pots side ..I tried Mouser and Amplified parts and nothing..the pot is for my cheap analog delay pedal,the Blend pot.
