right now, i am running a gallien-krueger rb700 mark ii into two gk cabs (gk mbx 1x15 and gk neo 1x15. however, i found a used ampeg hlf 6x10 in the area for $450, and i'm wondering if it would be worth buying that and running that with my head and sansamp bddi pedal instead of the 2 15's. the two cabs atm start to get farty when i barely crank it to 10 or 11 o' clock and i'm hoping that the 6x10 can handle my head+pedal better (and sound better too) i would really appreciate your thoughts on this. thanks!
