i did find two more brand new J202's from Mouser and installed them in the sockets. the pedal sounds pretty good but IMO could be improved.

what mods did you do?

just for experimentation, while waiting for the new J202's, i socketed the Jfets and installed J201's in their place, and it sounds exactly the same. Has anyone else built this circuit and is happy with the result? I certainly am not.

i bought the non smd versions. i'm out of them right now but just ordered some more of them.

yes, they're definitely J202's from Mouser. VCC is 9.29V.

they're definitely J202'S (from Mouser). I'm using a onespot power supply.

Q1 pin 1 Drain: 1.016V Q3 pin 1 Collector 2.678V Q4 pin 1 Drain .734V IMO, those seem really low for the Jfets.

the distortion in my build (which i've checked multiple times for errors and found none) just doesn't sound good at all to me. it really doesn't clean up well at all either.

it might help but the distortion doesn't sound right to me either. at least not like the online demos.

i built one using all of the correct transistors and components that i ordered from Mouser, but for some reason it doesn't sound like any of the online demos of the original pedal at all. i had high hopes for it, but unfortunately, i find it to be unusable as a pedal.

i'd like to remove a lot more top end since i find the circuit to be way too bright and fizzy. any ideas?

me too. maybe it was because that i completed the PCB at 4:00 am, but there's really no excuse for that.

i've built quite a few of them (etched my own PCBs for them) and found that the circuit is VERY particular on the choice of J201's used in it.

thanks Eric S! i reverse it and it's 100X better now. i feel like a moron doing that.

wow. good eye! thanks, i'll have to correct that!
