[quote name='fatback' timestamp='1328713624' post='1531541'] Thanks for the thoughts. My amp does go down to 2, as it happens, but the point I'm getting here is that the gain from the 4 vs 8 probably isn't worth bothering with, given that I've already got a sensitive cab. I was thinking about this mainly cos when I raise my cab on a stand (to avoid feedback from the upright) I lose a lot of oomph. So i was idly wondering whether a lower impedence cab would free up some headroom. You can see that a two cab solution couldn't work for this. Most likely, i'm going to try raising the cab by a lot less and hoping it's as effective at avoiding the feedback demons. Pity, cos raising the cab totally avoids any problem even at very high volumes.

I use one, it de-couples the cab from the floor and thereby removes unwanted resonance as well.

i witnessed the destructiion of a Marshall Amp, 4 x 12 cab in the Cavern Liverpool Circa 1966/7 so he was alive then....
