Hello, ive recently bought an ashdown mag 4x10" 250 watts bass combo second hand and im having a bit of trouble with it. I realy like the sound of this amp but when i start to turn it up the sound becomes quite harsh and not very good, could this be because i could have my EQ on bad setting? Or do i need another cab (i was thinking of getting the mag 1x15" but i dont have the money at the moment.) Or is there anything else i can do to get rid of this sound at high volumes? EDIT: The bass i am using is an epiphone explorer bass but i am will be getting a fender jazz soon, will this change make any differance to my problem?
