built this if you want to confirm! i decided to go with a J201 and Bat41's and a Led+4148 combo. its kinda weird having the reverse taper for the filter as im used to the normal one but meh, i'll get used to it, its usually set and forget for me anyways!
Thanks Andy. I'll tag it. If you are looking for the schematics, they are in the PedalPCB forum. https://forum.pedalpcb.com/threads/jhs-3-series-overdrive.4274/#post-34507
brother, please indulge us with the JHS moonshine, thanks for all the work you do, I admire you a lot brother http://www.pedalpcb.com/docs/BootlegOD.pdf
n00b question: I can't find the PF5102 except for silly money. I assume I could use J202 (the original on JHS's circuit) or something like the 2n5457, 2n5468 etc or NTE458 instead? I'm going to socket the transistor so swapping out will be easy anyway. Thanks!
I've had two separate goes at this with consistent flaws... something's not quite right...the sounds is very starved like there's not enough voltage or something... And the switch pops loudly. It's so similar to the standard rat though!
Any help with this would be much appreciated as I'd really like it. Is there perhaps a wrong way to wire up the filter/switch off row j? I've tried linking both with two wires and also linking them in sequence... either way I get the very weak starved distortion. (Fet an IC are verified as ok)

ReplyDeleteHaha!! Youve been doing some awesome work man. Any change of the pg-14??
ReplyDeleteOh! Forgot the PG-14. I'll give it a try....but it looks like it basically a JHS Haunting Mids V2 into a Wampler Plexi Drive style circuit?
DeletePeople already traced those? Was pretty sure from the sound demos already that they're going to be rather shameless clones.
ReplyDeleteJHS posted the schematics for all of them, so there was no need to trace.
DeleteMDS, You got a source for those schematics? tried looking but cant find anything
Deleteso basically a modded turbo rat?

Sounds great this one! I notice they've got side A and B of the Dualist on PedalPCB. Any chance at some point? All the best.
ReplyDeleteBen
Would love to! But sadly there is no schematic included in the build doc (yet)...

DeleteThanks, man.
DeleteWill post a layout in a couple of days.

ReplyDeleteIt is an output buffer so it doesn't generate any gain. So J202, 2N5457, 2N5458 or J113 will work just fine as countless other J FETs.
DeleteThanks for the really quick reply :)
DeleteI build it sounds great but a get a big increase in sound with the loud switch about a 35% jump anyone else get thi
ReplyDeleteThat switch choices silicon diodes or LEDs. The LEDs has more volume that silicon diodes (and less distortion). So it should be normal.

I've made the standard rat with good results....🤔
