I am the original owner of this amp, acquired in the late 90's; in every cosmetic sense, it is mint.
One of the earlier modeling amps that also had tubes; players were very passionate about these at one point: very loud, well defined tones, built like a tank - weighs 70LBS.
So what's the deal? It started to have problems soon after purchase: not always turning on, signal cutting out, etc.
As I had a ton of other gear and lots of playing to do, it sat. And sat.
May need a tube (?) may need some internal part (?)
If you are a electronics guy and like to fix things, or if you want parts for a JM150 that you already have, this may be for you.
Has less that 10 hours of playing time in over 35 years. Brand-new Celestion speakers and other components for parts.
I'd like to think that someone can fix this old girl, as she still looks awfully purty...
Come picker her up!
