If this design works as it is, the problem starts when you want to make changes. I've tried everything, it's percussive and a bit dark, almost distorted, but that's the way it is, perhaps changing the input and output capacitors clears the signal a bit, but no more than that.
I think Michael was right about the foot switch wiring. Hard to tell exactly what’s going on there. Look up the Schaller trem thread. I left a link for the wiring that I use most. That could be the issue with both layouts.
hi Loyd sorry for the delay in responding, experiment with 100k, 250k and 500k. finally i stuck with 250k plus a 100k series resistor between the negative pin of the 4.7uf capacitor and the 33k resistor to not make it so dark and percussive, this softens the sound with increasing depth
Mine has the same issue as Ian's, being super quiet. While troubleshooting I noticed it passes a weak clean signal with no transistors installed and no power plugged in. That can't be right, can it? I've also noticed removing Q1 makes it slightly louder and functional. I've given all the voids the standard stabby test so there shouldn't be any solder bridges, nor do I see any errors on my part.
This layout has an error in it. The 100k resistor to the right, beside the 33k and 43k, needs to go down one space and connect with the collector of Q1. This brings up the volume, but it distorts very badly.
i built it and it sounds great
ReplyDeleteHey Manuel what pot did you end up using for the sweep
DeleteThanks Manuel. Tagged.
DeleteManuel did you use this layout? What are your secrets? lol I can't get this thing to work, but I want to. What transistors?

ReplyDeleteI'm staring and staring...mine looks right, but like the Schaller, it's whisper quiet....

ReplyDeleteI use the skreddy method.👍👍
ReplyDeleteOh and I’m dumb. 100j is in fact code for 100nf. I have lots. Never thought about it. Smirk

ReplyDeleteIt's time to shoot the moon🌙
DeleteI have to say thanks to your demo of the Vico Vibe I'm most likely building that one.
