    Acetylene 2nd Try

    Ok I ran the audio probe. 1 = Silent 2 = Silent 3 = faint but signal distorted 4 = loud, buzzy, strong signal 5 = not as loud but signal there 6 = not as loud but signal there 7 = not as loud but signal there 8 = not as loud but signal there 9 = not as loud but signal there 10= not as loud but...

    Acetylene 2nd Try

    here are the voltages I measured for yellow dots. Seems like a drop happens at Q1 also across the IC1. I need to build an audio probe to measure signal at red dots. For Q1 that should be at 4.7 V on the collector correct?

    Acetylene 2nd Try

    Hi there. This is my 2nd attempt at this build and I feel like it generally went better until final checks. I pre checked and tested all components to spec before installing. The pedal only lights up the boost side, LED is bright, clicks off and on. No sound on bypass and no LED on and off...

    Originally yes. I was very careful to bend the tabs.

    Pharmacist

    Ok. Updates. I removed the red insulating material and looked through all of the solder points for any joints that may be cold. The good, I am getting closer. The pedal now will pass a sound on bypass. When I turn on Footswitch 1, there is no sound, LED is bright, and none of the pots seem to...

    I will pull the red insulator out and see if that helps.

    Pharmacist

    Good evening! I was successful in completing one Pharmacist build but the second one is not going to plan. I am running a check on resistor values and finding quite a few (10) are bad. My questions: 1. Grounding, is there any reason to have an insulator between metal case and pots? Case and...

    I will check that. Thus far, dead.

    Acetylene No Sound

    Ok so I traced the circuit, repaired the cold joint on one of the capacitors and was able to get a sound in true bypass when off. When on, I’m getting just a massive hiss/squeal and when I touch the case it changes hiss. Is it possible to have a ground issue with a pot or something?

    No. Tracing the circuit.

    Acetylene No Sound

    There was a cold joint on one of the capacitors. Sneaky!

    Acetylene No Sound

    For the Acetylene build, I’m not getting sound but I am getting LEDs off and on with foot switches. I’ve been troubleshooting and think it’s probably a ground issue. However, Is this the correct direction for the ICs? Any help it appreciated.
