Im just about to install it and was wondering if a switch could be installed on the outside of the wah to switch the FWR circuit on and off? Where would the switch be installed circuit? eg: in series with the 9v input to he FWR, would that work?
If it is installed correctly, there is no need to shut the 9V power off because it shuts off when input is unplugged. If you want to bypass the FWR you can install a toggle switch. Think of it as a bypass within the pedal. Unless you know some electronics and can figure it out, you should have it done by a qualified technician.
