So I went in to GC today and picked up one of the new Ampeg BA210V2's with a 15% off coupon so it was a pretty good deal.Earlier in the day I was texting back and forth with someone selling a Ampeg BSE410HLF on CL for cheap $125.I went into GC with the intent of looking at the BA or a head to power the 4x10 the only one they had was a PF500.I waited at GC for this person to call me back for an hr.Got tired of waiting and bought the Ba combo,on the way home got a call saying come and get it.So now I have the combo and a 4x10 cab,Dilema,should I just return the combo and get the PF500 or keep the combo and buy a head at a later date? The cab is a 4ohm 400 watt 800 watt program what exactly does that mean?
