This is a 1x12 20 watt all tube combo amp. The power amp uses 2 EL84 tubes, and the pre-amp uses 4 12AX7 tubes. It has a footswitch for changing channels and turning reverb on and off. You can choose between a serial and parallel effects loop.
This is a very good amp for classic rock styles if you plug straight in, but I use a Line 6 POD XT Live with it.
