Since I got the whole noise/hum issue worked out on the new setup. I've been doing some playing, at pretty good volume and checking out different heads with different cabs. The Splawn slant cab with Creambacks, sounds great. The Marshall cab with 75/76 Blackbacks, sounds AMAZING. But, the Splawn straight cab with Eminence Governor and Man O' Wars just doesn't sound right. Very bright, and fizzy compared to the other ones. Is this normal for that speaker combo?
