Ok, it has become apparent to me over the years how speakers and cabs have an effect on your tone. Obviously Marshall cabs a quite popular, are some better than others? i see folks seem to liike either vin 30s or greenbacks. I currently have a splawn 4X12 with their small blocks, a Carvin 4x12 with their British series and a Avatar 2x12 with (I think, Celestion 75s in it. I run the Splawn cab with my Splawn obviously, but I was wondering if I should change speakers in the other cabs. I put a Private Jack in my PV classic 30 and it improved the thud sound I was getting with that amp when I hit a big chord, but it kinda sounds "wooly", so Im not sure if I like that. So Im considering another speaker for that combo too. thoughts?
