Works perfect !!!! everything works as it should !!!! sounds awesome !!!!! good condition !!!!! For an in-depth history and description please see ( wgs4.com/sleeper amps part 1 Randall rg80es ) This spellbinding short story lays it all out how Don Randall started out in California as Leo Fenders right hand man in the 40s, and later went out on his own in the 70s, and that in the 80s he created his masterpiece the Randall RG80ES the ES standing for "Extra-Sustain".. What Randall termed "sustain" is today called "High-Gain Distortion"!! This amp also has a secret weapon, the treble control knob pulls-out and engages an extra whallop of sustain (input gain) . This amp soon got the attention of Dimebag Darrel of Pantera, and George Lynch of Dokken and many more shredders. These also came stock with a factory installed over-sized hulking spring reverb tank that puts out the best reverb I have ever heard !! This amp works perfect!! and is ready to rock !!! will pack with great care, and ship fully insured. Thanks!!
