SOB success

[Dan0h]

Decided to do two at a time tonight. One SOB for a friend. One SOB for me. Boxed the friends tonight. Boxing mine tomorrow. Going to put it in a 1590xx with four extra large MXR knobs. Ridiculous but cool. Success number 6&7. I look forward to Friday nights again. ??

Where did you get your JFETs? I would recommend the smd version with PedalPCB adapter. Most J201s out there are fake.

I know. I also have some of the PedalPCB SMDs with mounts. But I got these from Mouser and I Trust Mouser. They sound awesome as well.

For ~$4 each they better be legit J201s.

Agreed, this was not one of my better choices in life. I had just unloaded some stuff on eBay and was feeling frisky...

So this is strange. I Biased all three trims to 4.0v with the DMM sounded great, then decided to tweak to ear and about 75% of each trim pot sounds great. Only when I get close to the extreme right or left of the trims does the sound go to poop. Has any ever experienced that before? The last one I made only about 5% of the trim range sounded good and the remainder of the twist sounded like poop. Are some transistors able to handle voltage differences better than others? Not complaining by any means, just curious about the huge sweet spots.

JFETs are notorious for being all over the place, looks like those $4 Mouser fets were worth it?

I have a small stash of good J201's only use them when SMD isn't practical

I have three of these left I think I’ll save them for something special. I had read about the vast fluctuations in transistors but it isn’t until you hear a bunch of them in person to start to understand it. I ordered a small pile of random GE trans and Diodes to try out in sockets. Let the exploration begin.
