Basically i bought this amp only about a week ago but i wasn't and am still not happy with the tone. Its really trebly and the notes are extremely piercing. The only way ive been able to get a rounder/smoother tone from it is by putting a compressor in the FX loop and turning the tone knob on the pedal down to nearly zero (the compressor is the cs-3 boss compressor sustainer). Is this a known problem? I've seen the demos and stuff online of the amp and it sounds awesome but when i play i can't get any kind of decent tone through it. Im using a blackstar 2x12 cabinet with no pedals in front to start with just to try and use the distortion of the amp. The guitar is the Jackson SLATTXMG with 85/81 pups. Any advice or suggestion would be greatly appreciated thanks.
