My Polytone lived at a steakhouse I played for 2+ years til the gig got "postponed" recently... at which time I move the poly to my main steady, where I usually carry the AI. For more than a year it seemed like the acoustics of the room were at fault for the funky tone I was getting. One night with the Polytone and WOW! That's what a bass is supposed to sound like. Compliments from the singer, which is a rarity. Don't get me wrong- the AI is awesome with a mic, and perfect for ebass duties on a small stage. Just digging the poly more with the realist on my basses. Anybody else on the fence about their funky little R2-D2 amp?
