Disdis

Hello.
I've bought a Disdis kit at musikkind.
Now that I have mounted it I have a 3,5khz silibance when the pedal is turned on.
Do you have any idea of what it could be.
Thanks a lot.

As I said in your other thread, I need to see photos of the board and voltages to help you, it could be several things.

You say sibilance, so you mean hiss, not oscillation?

I will post fotos later.
When I say silibance I mean a kind of pure 3.5KHz tone.
It's continuous and happens with a power  supply and with 9v batteries.
Thanks.
