Are we talking two guitars plugged in playing at the same time by your friend with 4 arms, or wanting to have 2 guitars plugged in so he can swap them over quickly without unplug/plug issues....?
Cuz lately we spoke and he asked me some questions He just want to play with his kid and want to have the same sound at the same time (he will be changing the sounds on the multieffect)
Thanx
