PHIL JONES BASS
The BRIEFCASE is not your usual combo-practice amp. The most striking difference between this combo and others is that it features an extremely clean and powerful amplifier and full range compact speaker that can run on AC or DC power. It can accept voltages from 100 to 240 volts by using the voltage selector switch, can run on an internal lead acid gel battery (not supplied) or even an external 12V DC source such as a automotive starting battery.
