    VHS, no sound, FV-1 issue? (SOLVED)

    Went through ALL my pieces last night: resistors and caps just to make sure EVERYTHING was the right value. I also added extra solder to a few pieces that I thought might need it. No luck. I'm starting to lose hope on this one and am wondering if I need to start over or just move on. I've...

    VHS, no sound, FV-1 issue? (SOLVED)

    pin 13 was 3.3. I put 0 down on accident. I edited the original comment. I noticed others had 3.3 on pin 16 as well. I rechecked it but turned on the switches this time. It read at 3.3 as well.

    VHS, no sound, FV-1 issue? (SOLVED)

    So, I noticed this build up of white crusty stuff along the VH-1. I used some contact cleaner to clean it off. An hour later and this was on there... normal? not normal?

    VHS, no sound, FV-1 issue? (SOLVED)

    Pins 1 and 2 do have signal. Checking voltages next. Never had to do that so I’m gonna look it up. I do have a good multimeter.

    VHS, no sound, FV-1 issue? (SOLVED)

    Update... Changed the 1uf cap but still not working. Finally made myself a audio probe. I’m finding the signal drops at the 3rd spot in the FV-1. I don’t know if the issue is with the FV-1 that pedalpcb installed or with the 10u that it grounds to there. I’m changing out the 10u electrolytic and...

    VHS, no sound, FV-1 issue? (SOLVED)

    I don't think the 1uf caps are the issue in and of themselves because they are only in the signal path. I did recheck them and the legs aren't touching anything they shouldn't. HOWEVER, all this talk about the 1uf caps made me remember I had to pull one of the caps a little hard in order to get...

    VHS, no sound, FV-1 issue? (SOLVED)

    So, I built a 2 in 1 pedal. It’s a VHS going into a Phase II. I’m getting clean signal though the pedal. The Phase II works perfectly. The VHS, when I engage it it gives me a hiss sound and no bass signal. I notice when I switch on the Chorus or Reverb there is a loud pop. No pop when I switch...

    Trimpots in Phase II

    Thanks so much guys! Opened it up and saw the differences it makes. Before I was getting a lot less effect than I wanted. Now I can go from super subtle to deep warbles. Such a great pedal. I’ll keep messing around with it and find an exact spot where I like it.

    Trimpots in Phase II

    Can someone explain the function of the two trimpots in the Phase II?

    Switch for diodes muff fuzz

    I had the section socketed. I had trouble getting the sockets out and broke them to get them out. After that I noticed it wouldn’t work right. I’m not sure where the problem is exactly but it’s definitely my fault. I don’t mind waiting on a board that doesn’t look so mangled. I don’t have a...

    Switch for diodes muff fuzz

    yeah. I figured that out! It almost sounds Tonebendery to me. However, I realized today that’s the only sound coming out of the pedal. I think I applied too much heat and jacked around too much with the diode spots for the 2nd clipping section. So, I’m waiting up on another PCB(waitlist) and am...

    Switch for diodes muff fuzz

    If I used D4, would the top go to the switch then the bottom would be going back from the switch?

    Switch for diodes muff fuzz

    I’m wanting to add a switch for the second clipping section for the diodes on the muff fuzz. I want to be able to switch between LEDs and the regular setting. What would be the correct outgoing and input spots for that? I figured they would be the two top ones. I was planning to use an SPDT.

    Amentum Boost/EQD Arrows for Bass Mods

    thanks for your suggestions! I will try them out and post back on here to let everyone know how it goes.

    Amentum Boost/EQD Arrows for Bass Mods

    Yeah, I was planning to socket Q and start with the 2n2222a. I'll try whatever else I have with me. It is a tiny circuit so I don't how much that limits my ability to experiment. You think changing C2 would make a difference as well? I'm very new to this and am definitely still learning.
