Chad Sterenberg lists la dispute's gear in an email. He says Whittemore uses a 5150II Head through Marshall cabs. "Kevin plays an SG (guitar) through a 5150II head through Marshall cabs. His pedal set up is about the same as mine: tuner, noise suppressor, delay. But he uses a Boss tuner and delay (DD7 I think)."more
Compared to the 5150, the II has slightly less gain, a more open, less compressed and tighter sound. It's slightly more versatile than the 5150 due to having a 2nd independent channel that can act as a clean or crunch.
