The mighty 388!! This is serial #388 made the first or second day of production in 1982! This very rare JCM 800 is equiped with extremely rare and basically extinct GE military spec 6550s tubes and gold conections throughout. This head was just re-worked completely including new old-stock 6550s (1985 vintage tubes) and a complete re-soldering of the curcuit board. It cost more to refurbish it than I paid for it new!! I've had it for 25 years!! Amazing sound!!
