You Can make one yourself, using the following parts: 2 x 1/4″ stereo
plugs (+ cables), 2 x 1/4″ stereo jacks, 1 x dual color LED (Green, Red), 1
LED (Green), 2 x 510 ohm resistors and 2 x DPDT swithches. The circuit is as
follows:

Connections are stereo 1/4″

RED Jack:
Tip – -6.2 Volts
Ring – Channel 1 (Hi Gain)
Gnd – ground shield

PLAIN Jack:
Tip – Channel 2 (Clean)
Ring – Reverb
Gnd – ground shield

-6V attaches to the cathodes of two LEDs. RED/GREEN for Channel and GREEN
for Reverb.

Gnd attaches to the common lugs of the two DPDT switches and the box.

Anodes of two LEDs attach to 510 ohm resistors.

Channel Switching:
GREEN LED resistor attaches to DPDT lug that goes with Channel 1.
RED LED resistor to DPDT lug that goes with Channel 2 .

Reverb Switching:
Green LED resistor attaches to DPDT lug opposite the Reverb lug and ground.
(When Reverb is grounded, it’s off) so this is an On/Off thing
