    Blue Shoe Gai Pan Distortion Jfet Bias

    Hello, Are all three JFET in the pedal supposed to be biased to 9v? Q2 has 18V going to it, and I can't get it lower than 14V with the trimmer. Thanks!

    Relay Switch question

    Hi, quick question. With this relay system : https://www.pedalpcb.com/product/pcb393/ should my switch be normally closed or normally open? Thanks!

    Missing Build Docs / Schematics

    @Robert you know what Pedal PCB should do? Post complete build docs at the same time as the PCB release. I'm done buying PCBs with no parts lists or schematics or drill templates. It's just pathetic at this point. Need some help getting caught up? I'd do it for minimum wage! Seriously.

    Looking forward to making the tone generator. Will require an order of SMD parts. Could we get a list? Also, what is a “milled” enclosure?

    Minnow voltages

    Well, I am passing signal through the effect now, but it doesn’t seem quite right. The S/H is really slow even when turned up all the way. LM13700 6 -6.3V 11 +6.65 The op amps are both -6.55 on 4 and +7 on 8. There’s something weird with the voltage coming in I think. As before, supply is...

    Minnow voltages

    LM13700 6 -6.32v 9 0v TL072 1 4 0v 8 +7v TL072 4 -3.5v 8 +7v My supply voltage is 9.46v until I connect it. When connected it drops to 7.3v. Is that normal?

    Minnow voltages

    Hello, I have been trying to build a Minnow. My first attempt had a few issues, so I started over with a new PCB. One of the issues was that the +8 and -8 were reading +9 and -9. On this new board I decided to start by just populating the power section, and I still have the same problem. What...

    Minnow (FSH-1) schematic question

    Can someone explain/teach me why the buffer for the second opamp is just hanging out in space like this. Does it just mean that the pins are not used? Thanks!

    Power supply voltage drop when connected to pedal.

    Q: Why the hell does the voltage from my power supply read 9.48v, but when I plug it into the pedal it drops to 7.98v??? A: The reverse polarity protection diode is probably backward. Just wanted to document this for any future travelers. Spent a good hour troubleshooting this. I have a large...

    Aion PCB's

    I'm a complete novice at PCB design, but I wonder, wouldn't it make more sense to lay out a PCB with the parts that are close to each other on the schematic to be close to each other on the PCB rather than lining them all up to look symmetrical? Honest question. Maybe Pedal PCB boards take both...
