The different options for controlling the Thunder 50 amp remotely:
1. Two-way footswitch (e.g. ENGL Z-4): Connect it to the amp (to jack 15) via a stereo ¼" cord.
Functions: Clean/Lead, Crunch/Lead. With this solution, you can't activate the channels Clean, Crunch
and Lead directly, i.e. this requires an intermediate switching operation.
2. MIDI-Switcher (e.g. ENGL Z-11): Connect the unit to the amp via two stereo ¼" cords. The
buttons on the Switcher control Clean/Lead and Crunch/Lead. If you program the diverse channels
to different MIDI program locations, you can activate all three channels directly via a MIDI board
(e.g. ENGL Z-12). This type of control option is extremely versatile, we recommend
it highly if you intend to use the amp in conjunction with a MIDI system (e.g. MIDI effects devices).
