I've always has great luck with Ashdown amps but recently picked up a "new/old stock" Ashdown Abm 900 Evo III. While the right (top) speaker outputs sound amazing, the left (bottom) Poweramp sounds like there is literally a fuzz pedal running parallel with the actual signal from both outputs. Anyone else have a similar issue or insight? The dealer basically told me they can't help.me, and to contact Ashdown who I am in some correspondence with. Not that I NEED both poweramps, but it's nice to know it is functioning as it should!
