Vintage 1964 Pre CBS Fender Vibro Champ. recently serviced and will include paperwork. New old stock RCA and Mullard Tubes. Upgraded to a 3 prong power cord. Original speaker was changed out to a Weber Alnico speaker that sounds awesome! The rectifier was converted to a solid state but this is completely reversible by the removal of a few small parts. This was a common mod that was done so high output pickups like humbuckers would not blowout/fart out with the small speaker that these come with. I am including the rca rectifier tube as well. This is a very simple mod that included a few resistors no drilling or anything permanent was done to affect value. Sounds wonderful for bedroom and studio use. Can get the sparkling cleans from 1 to 7 on the volume and dirty cranked sound when you put it on 10 without going deaf. The tremolo works and sounds perfect! definitely has that mojo that you want from a vintage amp. i have never came across another one in this condition. These are getting harder and harder to find. I am downsizing my collection my loss your gain. Dont hesitate to message me with any questions.
