Mad Professor


As the name implies, the Mad Professor Old School 51 RT-2x12 is designed for classic guitar tones, from the '50s to modern times.

You are able to get legendary tones from both sides the Atlantic that suit country, pop, rock, reggae, soul, hard rock, alternative and every other style-name the clever marketing people at record companies come out with.

No need for channel switching as these classic tones from clean to distorted are easy to get by adjusting your guitar’s volume and tone knobs. Coming from a pedal-manufacturing company this amp takes pedals very well.

The amp has built-in reverb and tremolo for the final old-school touch.
