How do I wire a custom cable to switch the Randall RH150G3?
From a TRS jack connected in the G-major switching output:
TIP = Pin 1
RING = Pin 2
Sleeve (GND) = Pin 5
- Connect pin 3 to ground for permanent reverb.
- Connect pin 4 to ground for permanent boost.
Pin assignment of the Randall custom plug:
Pin 1 : Clean/od
Pin 2 : Od1/od2
Pin 3 : Reverb
Pin 4 : Boost clean
Pin 5 : Ground
Pin 6 : ?
