What to do with pedals with a loud bypass?

Post by Andrew »

So a certain delay pedal that I have gets used frequently on a daily basis, the problem is that whenever I set on the bypass footswitch there's a noticable volume popping sound and just detracts from the atmosphere when playing and it's just an annoying sound. It's currently in my FX Loop.

I'm going to be stupid and ask for some advice about these sort of things. Cables? Bad wiring? Powersupply?

Cheers.

Does it pop every time or just the first time after you turn it on?

I have a pedal that does this too, all the time.
I'm also curious how you could fix this, put in a new switch maybe?
Another thing I noticed or read somewhere is that pedals that have this problem are generally true bypass, it's one of the disadvantages of true bypass.

you can try to add a pull down resistor from the input/output cap to ground. somethign big, like 1M.

if you google this you will find many discussions on diy forums regarding this exact issue. Its usually curable.

Thanks Scott, I guess I'll have to take it to the fx doctor then.
The funny thing is not every pedal does it apparently (not even if it's another specimen of the exact same pedal, mine is a Lovepedal Pickle Vibe) so that makes it quite weird.

Ya part of what makes it 'weird' is that it likely will get better/worse depending on whats plugged in in front/behind the pedal. Perhaps that's why some people report problems and others don't. Basically what JC said, it could be caused by a combination of things. |f you can find a schematic i could probbaly make a better guess as to whether or not adding pull downs will help before you pay someone to do the mod.
