Joyo ATOMIC British Classic Rock 20W RMS Tube Guitar Amp HeadThe AtomiC from Joyos BantamP series is a very compact and portable 20 Watt head. There are few amps that have remained almost unchanged throughout the years. We immediately think of some American classics, but one amplifier stands out. There is this amp that gives you the British clean sound, the one that has hollow mids and a beautiful bell like character. This amp delivers a brilliant bite and has shaped the history of rock music through the ages.
