I really hate to let this one go, but I'm moving in a different direction with amplification right now.
Great amp with upright, electric, and even guitar. Tons of power! Excellent condition. I purchased it from luthier Mike Olivola earlier this year. I've gigged it quite a bit, but taken good care of it.
Ships with a Gator case. One of the shoulder strap latches is broken, but it works fine as is.
$495 plus shipping, CONUS.
