That high-end studio amp from London Power can be rolled back to the [u]micro[/u]watt level!
BadHorsie, this is a bit like negotiating arms reduction among a bunch of combatants. If all of the band members are using small amps, there's less hassle about drowning each other out. And the drum kit doesn't get drowned out, meaning you don't have to mic them. (Your sound man will be eternally grateful!)
