Presently I'm running a Hartke LH500 with two Hartke Hydrive 112's. Very versatile, I can use one or both when needed. I like them very much. The band bought on-board a loud drummer, no problem. Now we have bought on-board a lead guitar with a Line 6 amp with 4x12's that plays extremely loud. Before all of this happened I was looking to downsize from the 12's to a one premium 15 cab at 4ohms that can give me the max from the amp I already have and have the low end of a 15 tone plus have one bass cab with wheels to haul. I was looking at a Fender Bassman Pro 115 but it's rated at 8 ohms. The Hartke's have a 4/8 ohms switch which is nice. I don't plan at my age to haul two 15in cabs. Maybe I should keep what I have and be satisfied. Problem is, like many of you, we are never really satisfied. Any suggestions?
