Excellent condition. This British style OD/distortion pedal is extremely rare and does everything from low gain crunch to high gain distortion. Great dynamics and touch sensitivity. The Fat switch is very subtle and is more noticable with single coils. I can't really hear much of a difference with my humbuckers when it's engaged.
This pedal needs 9v 250 ma and does not like sharing power - it internally converts 9v DC to 280v DC (Rodenberg's Analog Virtual Tube Circuit technology) so some of the components won't work if it's not getting proper isolated power.
