A solid finisher for any preamp-equipped rig or multi-effects modelling unit, this potent stereo power amplifier can be installed to deliver 200 Watts per channel at 4 Ohms, or 100 Watts per channel at 8 Ohms.

BOSS' WAZA Tube Amp Expander ensures you get the best out of any tube amplifier with a power output of up to 150 watts. It's a load box, an analogue power stage, a mic emulator, a cab simulator, an IR loader, and a recording interface in one!

The Pedal Baby by Orange is a compact, lightweight and robust Class A/B power amp. It's specially designed for touring guitarists who get their sound from effects pedals, modellers or digital multi-effects.

The 100-Watt-strong Blackstar Dept. 10 Amped 2 power amp supplies built-in drive pedals, a preamp section and a potent multi-effects processor - packing your every whim into one board-ready unit.
