Thank you for viewing. This is a listing for a Burriss amp Boostiest II. This unit is a rare piece, a hybrid model with the following features: * Handwritten signature of the maker and "NAMM 2011" written on the bottom plate. * Boostist II exterior with a 2.5 specification internal circuit. * A prototype/demo unit that was not commercially available. This is a rare piece and a valuable collector's item. The pop and cute appearance is also a highlight. I purchased this at a musical instrument store and had the internals checked. It appears to be a prototype made for the NAMM Show, with a Boostiest II enclosure and a Boostiest 2.5 circuit board. It functions without any issues. The TS-type overdrive on the left side is excellent, and the booster on the right side offers a wide range from a hi-fi clean booster to a treble booster, each usable independently. I am listing this item because I want to offer it to collectors and those who appreciate its value. I am open to price negotiations, so please feel free to comment. Functionality confirmed, no scratchiness or defects, signature on the bottom, original box included, with instruction manual and stickers.
