Valve pre-amp. 12" Celestion speaker, spring reverb. 100W RMS. Double channel, each one with clean, gain and distortion control. When the clean volume is raised over half it reaches a natural distortion which can be regulated by hand-touch. If played gently it will remain clean even at high volume. Good dynamic distortion. 3-band EQ, furnished with footswitch, send and return for effects. Great sound quality.
