Hiwatt FS200LJPB Footswitch

This is the universal footswitch in the Hiwatt line: two buttons, pedalboard-friendly, with independent polarity switches per button so it stands in for any of Hiwatt's two-function footswitches.

That covers the FS201, FS202 and FS203, which means one switch can follow a player across amplifiers instead of one per amp. On the three-function Super Leeds amplifiers it switches gain and channel, or reverb, rather than all three at once. It connects to any compatible TRS amplifier and carries status LEDs.
