Anyone Here Blackface a Silverface Fender?

[Paul Marossy]

On the simple amps, the remote Reverb switch *has signal on the wire*. It *must* use shielded wire, or that yard of cable will suck-up all the buzz and pops in the room.

Later amps tend to DC-controlled switching and generally do not need shielding on the switch cable.

While we are here: the TREM switch on simple amps generally does not have to be shielded. It is either a simple form of DC switching (debiasing the LFO) or acts as dead-short when Trem is running.

All of the reverb wires in my Twin Reverb are shielded RCA cable, footswitch included. The wire on the footswitch that is for the vibrato is unshielded.
