I decided to get rid of my combo amps this afternoon. I have two heads & one MB Traveler 102P cabinet. The 2x10 is 8 Ohms, so I thought that if I were to buy another cabinet, I'd want it to be 8 Ohms, so I can pair it with my 2x10, should I ever want to. The trouble is, I want a single, or at least something small. Would I be causing sacrilege to run another 10 (or 12) paired with the 2x10? Any suggestions? The heads are an Aguilar Tone Hammer 350 & a Hughes & Kettner Tubemeister 18. Another reason I want an 8 Ohm cabinet is because the H&K's minimum Ohm rating is 8. I don't plan on running the 18 watt tube head with two cabinets. It just doesn't have the cajones for that. I've assumed I'm better off buying a bass cabinet that I could use with both heads, whereas I think a guitar cab might disintegrate under the flex of bass frequencies.
