Maybe we need a sub-1 watt amp for the guitarists? I've played electric guitar and mandolin through an old Pignose battery amp in mainly blues sessions with acoustic players and it all seemed OK, perhaps the advantage of this is that it gave a nice clean to slight overdriven sound (which is what I like) at low volumes whereas it's distorted sound is bloody awful!

We've concentrated mainly on guitars so far - any experience with keyboards/synths? I'm guessing there isn't the same need for high gain amps to give an overdriven sound here...
