    Chop Shop Troubleshooting

    Not pretty! But I've reflowed and checked between solders for bridges. Also, I left the legs on the transistor for now.

    Chop Shop Troubleshooting

    I know this is prob a low priority, but if anyone has any input I'd appreciate it. I looked at the voltages to the Jfet last night and it's getting through.

    Son of Ben (Benson Preamp) Modifications Thread

    Also…if you’ve built one and biased it to spec, go back in and do it by ear just to see. I just went back in and found that i liked it much better at a very diff voltage for 2/3. Might be because of my bass mods or because I’m playing bass but I was surprised to find a very diff sweet spot.

    Chop Shop Troubleshooting

    Also…ground to pad gives me 9v, but when I try to bias the jfet—just to see if I could—i get nothing. Is the jfet maybe not grounded?

    Chop Shop Troubleshooting

    @Robert I did more testing and was able to trace the 9v through to the end. Not sure what the issue was before. Still, the pedal isn’t working. I did an audio probe and found that the signal dies at C4. It makes it to the jfet—one side—and then doesn’t show up at either of the other poles. I...

    Just one end. Should it be passing through? That may be it...

    Chop Shop Troubleshooting

    I think that part of my question is how I would go about following the voltage path based on the schematic. Clearly, it seems like the voltage is dropping somewhere or being shunt or not grounded. I know how to follow the audio signal, but it's less clear on the voltage path. Actually... took...

    Chop shop quick question

    Having an issue getting mine running and just started a troubleshooting thread if anyone has insight: https://forum.pedalpcb.com/threads/chop-shop-troubleshooting.26277/ TLDR: seems to pass audio but voltage isn't passing

    Chop Shop Troubleshooting

    HI all... I build a pedal or two a year, so I'm by no means an expert, but not a total noob. I just put together a Chop Shop/Barbershop drive. I populated the board with components from smallbear and reused a power jack and in/out jacks from an old build. Got it all set... and no signal...

    Chop shop quick question

    Whelp... put the transistor in the wrong way and shredded it while trying to take it out. I have a 2n3904 and a 2n5089 as well as a bunch of muff transistors... would any of those be a decent sub for pn222a?

    Beautiful PCB on the production model.

    Chop shop quick question

    Whew... settled that... but, do you need to match the jfets for the build? Or does biasing achieve that?

    Chop shop quick question

    Just ordered my components and of course accidentally just ordered one jfet... doh... seeing if pedalpcb or smallbear still has my order in hand.

    Chop shop quick question

    Thank you! Going to make this for bass. I have an old Plumes build I'm just going to sub it into. I've gone through a bunch of bass OD's lately and feel like this could be what I'm looking for.

    Would 2N222A work?

    Chop shop quick question

    Actually... I have a chop shop question as well: the notes say that you need a PN222A transistor. I'm ordering from smallbear and you need to order a 5 pack. You can order a single PN2925, though. Is that an okay substitute?

    Bassifying a Muff

    I need to post it... but I had to give it some time and really listen. In the end, what I have been using is two different CMC Muffs. One is a tall font with Mids with the coupling caps replaced for 180n and LEDs (green/clear) in both sets of clippers. I am also using a Violet Rams head with...
