DA5, I'm in a house and my neighbors are both at least 45 feet away, and I never take it off the .5 watt setting. Nice amp, comes in a bunch of different colors now too.
Guitar Center here in Tucson and in Scottsdale has always been great, courteous, fairly knowledgable, good prices and great return policy.
I would never compare those two stores to any Wal-Mart I've been to.
