How is the volume on the 330? A big problem for me with my 360 was volume.
I'd try turning the volume up on the amp, if that's not loud enough get a twin, if that shakes the house your getting there, and if you want to go totally voluminous, and put the twin on 6-8 then you will surely succeed! Buy a 20 ft Ric and a 20 foot Fender amp like Mr Marr dreams about, I think that would do the trick very nicely don't you think???!
Solving big volume problems, needs big solutions....... buy a huge amp or two!
