Question I have a Marshall JVM410 and it has four channels on it. Is it possible to add effects in a preset with the amp switching Answer The JVM410 is MIDI compatible and can store presets. G-System Can send MIDI program change messages to the AMP to recall the different channels. This can be combined with internal G-System effects and pedals connected into the loops.
