Re: Amp babble
You can play almost any gig other than a metal gig with a Vox AC15 (15 watts of pure class A tube amp) - anything louder than a Vox AC30 is simply going to give your sound man problems with balance on stage, and if you are micing your amps through a PA, in actual fact the lower output your onstage amps are, the better control of the overall mix the soundguy will have - they HATE 100 watt amps, for very good reasons.
At your end of the scale, valve amps simply sound better when you drive them reasonably hard, and you stand more chance of really driving a 30 - 50 watt amp than anything bigger (and MORE chance of driving something smaller). I don't know if more speakers make you louder per se, but they make it easier to hear yourself on stage - likewise open back cabinets are less directional than closed back - so as you move around the stage your chance of hearing yourself is improved.
