Yamaha JX40 1x12 40 watt guitar amplifier Excellent

Lightly used never gigged. Sleeper candidate for best solid state amp ever made. fully functional. Pots have been cleaned/lubed. the push/pull volume pot works as it should but can Slightly crackle when adjusting while it is engaged/pulled. Silent when not adjusting. If I keep this amp the only upgrade would be a speaker upgrade. The caps appear in good shape (at least cosmetically) and the amps sounds great so I would leave caps as is until a problem occurs, which for this era of Japanese manufacturing may be quite some time If ever.
