Ampeg R-15R Supereverb 25W 1x15 Tube Combo Amp (1964) Kalamazoo Aside from the changes notedA super rare vintage 1964 Ampeg R 15R Supereverb tube combo amp in great cosmetic condition. Produced for barely a year, the R 15R is one of Ampeg's rarest models. What makes this amp even more special is its name. In early 1964, after receiving a cease and desist for infringing upon Fender's Super Reverb trademark, Ampeg changed the name of the R 15R to Superbreverb. This Jan '64 model retains the original name and is a rare piece of amp history.
