There's a gain switch on the back of my guitar pedal and I hear no difference when it is switched. It has the two choises of -10dBm and +4dBm. The manual is vague about it. Like i said I hear no difference and would like to know if anybody here knows exactly what the switch does?

Thanks.

sends to the amp(I think)

Could it not be noticable by the headphone port?

4dBm equals 2.5 watts of power

10dBm = 0.0001 watts of power

I think it's in relation to amount of power outputted. But then I'm sure you'd hear some difference =/

What exactly do the instructions say?

Mabye the difference is NOT apparent using the headphone port. Could that be the case?
