I have the Ashdown ABM500 EVO 11 with dual footswitch which is great to turn on the sub harmoniser and the tube drive, but the footswitch has no leds on so its difficult to remember if you are on or off !! Superb amp, here are my settings with musicman stingray 3 eq bass played eq flat fingerstyle. shape button out, bass 2 o clock mid 2 o clock, treble 3 o clock, sliders are all flat except the 1.2khz which i boost to full to add clarity and punch. Tube drive about 12 o clock, and if using it sub harmoniser on about 11 o clock. Any other settings out there ??
