I'm new to the EUB and will be using an Eminence to replace my traditional fretless electric for church services. Between songs, it was easy to silence the electric by spinning the volume knob down, but the EUB has no such controls. I'm sitting a few feet away from the amp, so it's not practical to pot it up and down throughout the service. So, question: Is there an on/off device (e.g. foot switch) anyone recommends that can be patched between the bass and amp? (I bought a Fender foot switch on eBay thinking it was the device I was after; turns out I was mistaken.) Thanks for the help!
