i know it's not a high gain drive but i expected to get a bit more than the very mild gain that it has at maximum drive.

I built the Mach 1 and it does sound very nice and transparent but IMO, it doesn't have anywhere near as much OD/Distortion with the gain cranked as the online demos show. Does anyone have ideas as to why?

i built the Mach 1 and it sounds very nice, but it doesn't seem to have anywhere near the same amount of OD/distortion with the drive maxed as the demo videos show.

i add a two way clipping switch by adding two 1N4148's and a .1uf cap to the third gain stage (C4/R13) to mine so i could get more fuzz out of it, and it's sounds great both ways/

just finished my acid rain build. personally, i wish it had more fuzz.

it sounds nearly identical. it doesn't have quite as much fuzz, and not as much output volume (but it has plenty of output). i assume that the J201's that i'm using aren't exactly the same spec, but they're VERY close to all of the parameters on the build sheet. here's a pic of it completed (i...

that was it. thanks!

i just completed the Nein Fuzz but it doesn't sound at all like my original Fairfield 900. It does kind of work but there's not much fuzz coming out of it. I used J201's (pcb type) and measured all 20 of the ones that I have in stock on my Peak DCA75 to match them to the specs as close as...

my build has plenty of output and sounds nice. IMO, it would be nice to have less distortion with the Dirt control at minimum though.

i've been using krylon matte clear on my decal clear coats. it take quite a fw coats to build it up . once cured, i block sand it with 1500 grit and buff them to a high gloss on my buffing wheel. IMO, it comes out great looking:

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.
