please help, Ive just bought a mkiv boogie and I am made up with over drive channels but clean channel is not so good.(All this about sounding like a fender is not happening)I have tryed factory settings but not impressed. anyone getting nice clean tone from one of these please let me know settings. The amp is loaded with a EV, the valves are jan phillips (these are low gain valves so should aid the clean channel). The guitar is ajohn birch fitted with humbuckers.
