Footswitch Pop

Post by Structo »

Anybody have any trouble with the OD footswitch popping when switching it off?

Mine is doing it. I'm not sure if it always did or this is something new.

I put a .01uF ceramic across the OD footswitch and that didn't do anything.

How about a large resistor from the switch to ground or across the switch?

My footswitch is wired like this drawing.

Got suppression diodes on the relays, caps on the relay coils, pop stop caps on the caps... ?

I have the diodes across the relay coils.

No caps on the relays.

I guess I assumed the popping was from the footswitch itself and not the relay.

As mentioned I put a .01uF ceramic across the OD foot switch.

I will try the manual switches and see if they do it too.

What do you mean by: pop stop caps on the caps?

A 1-M (or higher) from the output of a cap to ground can prevent a circuit from popping. A coupling cap hanging in space with no load on it will eventually have it's output climb to the point where there is enough voltage at it's output to pop. That voltage makes the pop when you finally do connect the cap to something. The pop is the discharge. Either grounding the cap at the output of a circuit, or hanging a resistor on it usually fixes this.
