This is a used Roland Cube 30 guitar combo.
It features 30 watts of power into a 10" speaker, loads of built in effects (chorus, phaser, tremolo and delays) It features 2 channels ( 1 clean, 1 overdrive) and 3 band EQ (bass middle, treble)
It also has a few amp models for different overdrive sounds on the second channel with it's own gain and volume knobs.
Just gone over by our tech so it's working perfectly.
Sounds great, it's small and really packs a punch!
