Simple amp that has many personalities. One word that describes this amp the best: dynamics. You can go from overdrive-laden riffs to clean picking with just lowering your guitar's volume pot or just by playing softer. Old School 21RT has built-in reverb and tremolo. Amp's reverb is based on Mad Professor's Silver Spring Reverb pedal.
Amp's designer Bj�rn Juhl went through the original point-to-point version of Old School 21 and fine-tuned it. They wanted to make the amp more affordable, so Bj�rn and Jukka M�nkk�nen of Mad Professor designed a PCB for it in cooperation with Martin Kidd from the UK. The components are exactly the same as in the previous version of the amp. Bj�rn himself thinks that this is the best amp he has ever designed.
