The Backline 100 is a 100-watt solid-state 1×12 guitar combo from Gallien-Krueger. A Lead channel with gain, volume, its own bass, mid and treble and a Lead 2 switch for more drive sits beside a Clean channel with its own volume and three-band EQ, switchable from the panel or a footswitch. A shared presence control, a VCV (Vintage Cabinet Voicing) switch, spring reverb and an effects loop complete it.
