chesseroo, it might be something like that. all though im not 100% sure what chuff is.

i will tell you though that i sure hope the replacement EP500 axiom is sending me dosent do this. i was under the impression that the EP500 can be played VERY LOUD without any distortion. well im not playing it very loud at all and it seems very distorted in some low bass scenes. my EP350 didnt even make this kinda of sound.
