I had a Made In USA Ampeg B2RE I used every day 5+ days a week for 4 hours a shot for gigs, at home practice and band rehearsals during a 7 month span without fail. My B2RE went with me everywhere my bass went across the land never letting me down - ever. From 100 degree outdoor gigs to freezing our tails off, it always worked perfectly. The B2RE is the perfect mix of the old Ampeg sound that made them famous, rock solid reliability and solid state ease of use / maintenance / weight.
One amazing thing is my amp always delivered an awesome live sound with plenty of punch to cut through any mix getting rave reviews from sound men and patrons alike. Volume was never an issue and depending on the gig I would bring one (for indoor) or two (for medium size outdoor gigs) cabinets and never had trouble keeping up with the
very loud twin guitar assault delivered by my lead and rhythm guitar players or our heavy handed drummer.
We played a mix of rock, southern rock and rockin' blues covers and the only times I ever felt the amp wouldn't have been enough we had professional sound guys running a big stage, light, FOH show for 2000+ people. The sound guys always plugged direct in the built in DI jack on the back which has a pre / post EQ option. Depending on my technique and chosen instrument of destruction, I can get very close to the sound of the original bass player on many of the songs my band covers and not switch gear or use effects all night.
My only complaints are quite minor, I would like to have a tuner mute and tuner out on the amp since it lives in a rack with a tuner and power conditioner.
For maintenance the only thing that has been done to mine is take the top off and blow out the road dust accumulated from live outdoor gigs. The inside is built like a tank and appears to have been designed by someone that used to repair a lot of physically broken amps.
If something happened to mine, I would buy another in a heartbeat without a second thought.
