Here we have a true classic. Small box JMP Bass 50 watt head from 1969/1970. Serial number is 3334A. Amp works well without any hums poppings. Amp has been serviced. Tubes have been tested, new back plate added, replaced dried capacitors and choke fixed to original specs.
Amp is visually in great condition, and also sounds great, healthy and rock´n´roll!
