Well I have the Maverick 2x12 combo so we might not be experiencing the same thing... I've never noticed such bassiness on my MIA Strat or my Schecter C-1 on the lead channel. Maybe it's a problem with the head or maybe it's just our ears differing.
I definitely use the lead channel for heavier...
Reluctantly parting ways with my Maverick combo... just don't have enough room for it in my new apartment. For those who aren't familiar with this amp, it's an out of production 2 channel amp that is great for a lot of styles. Amp is still in very good condition with some minor dings and wear...
