exactly, the presets from the mustang and the effects from the tonelab collide, i also have this really bad amp that i bought for like 50$ when i started playing and i use the tonelab on that one but the sound from the amp itself is horrible and i have been meaning to buy a new amp but i dont have a clue on which to buy. i think i want an amp that has a good tone and connects well with the multieffects pedal. i dont want a modelling amp
