Hello. I built a vintage univibe clone, SMD version, and it works flawlessly in regards to the vibe function, yet, there is some separate noise sneaking through. The noise is a swish swish swish with the bulb flash that is separate from the vibe effect sound. All other aspects of the pedal...

how to add a simple buffer to pedal? jacks? mainly from the buffer, im wanting to eliminate switch popping on and off.

I have a boost pedal, its going great, but the boost dial / pot, almost all the effewct comes on in the last 5 %, from about 7-10 is where everything happens, nothing before that. Ive tried A100K and A500K, and seems to be about the same. Would it be more than just the pot? Suggestions please.

Hello everyone. I have a general boost pedal. I want to add a volume / master volume control on the output jack, yet just adding A100K pot seems to take away some of the high frequencies, i.e. you loose treble (or brightness) while turning down the volume pot. I want to retain the treble /...

Im having trouble with a vibe build. Here's the thing. When i plug in the power supply, i see the bulb go brighter and deeper in the flashing mode, seems perfect, yet after about 1 second after i plug in the power supply it suddenly goes more dim, the depth of the flashing has gone much dimmer...

I have built a univibe. Here's the thing. When i plug in the power supply, i see the bulb go bright and deep in the flashing, yet about about 1 second it goes more dim, thus the univibe tone doesn't sound correct. Any ideas on power supply issues or what part of the univibe circuit controls...

Ok i changed my speed pot to a anti-log because the sweep was wrong (everything was happening in the top 10%), and now with new pot the sweep is great yet the pot change has made my bulb or the vibe effect not go so deep. lost about half the depth / throb. weird. Are the speed pots wired into...
