Im looking for a good amp that's relatively cheap. I play in a punk band with just a drummer and a guitarist. I want to be able to fill in the sound and im not sure whats the best way to go about this. my current rig is a gk 400rb combo with a 15inch speaker and an avatar b210. the guitarist uses a 4x12 with a 100 watt head, he has a massive sound that feels up a lot but i feel my rig doesn't compete very well unless i crank then i start clipping and overheating( overheated at my last gig and the amp shut off). i keep hearing about the ampeg pf500 and i tried it out but it doesn't seem that loud with the ampeg 15 inch speaker. i was thinking of maybe an acoustic 4x10 and a cheap amp head because im on a tight budget. id rather have a good head and ok speakers and upgrade to better speakers later. so yea what are good combinations of amp heads and speakers. i hope i gave enough details.
