Hi there I got an Ampeg SVT VR and an American Jazz Bass with Lindy Fralin Pickups. The bass sounds awesome on this amp except when I play the E-String real hard (By E-String I mean all the notes located on that string no the E in particular ) . It farts and distorts too much. With the other strings its no problem. Anybody had this problem or know a way how to solve this without reducing the volume? The cabinet is a 6X10 and I play the amp about 9 o clock bridged Thanks!
