I just bought a used JVM410H, but it didn't come with a footswitch. I do have access to a footswitch from a JVM410HJS (PEDL00055), but for whatever reason it doesn't like the JVM410H...even though AFAIK it should.
Can anybody suggest a solution, please?
The JVM410HJS pedal should work with the JVM410H, we would recommed the you reinitalise the amplifier details on how to do this are in the manual. If this does not work and you can change channel manually on the amplifier then the footswitch may be faulty.
