As a person who buys and sells gear all the time (I'm not sentimental about gear), I love my JP-2C and have no intention of selling it.
However, I would probably sell it very quickly, if I wasn't lucky enough to be in a position to be able to own my other higher-end gear simultaneously (Mark V, Axe FX II, Kemper). The JP-2C is not as versatile as these other amps. It does what it does superbly, but it can't do everything I need.
Something like the Axe FX can do everything I need, but it doesn't do it perfectly. Same with the Mark V.
It's like this:
I own a sportbike. It's crazy fast and handles like a dream; but sometimes the whole family needs to go on a trip. So I can get a high performance car, not quite as fast, but can do things the bike can't. Then again, sometimes I need to move large items, so I get a truck. I've never seen a vehicle that can do each of those things, as well as each individual vehicle can do its specific task.
I've never found this trait in an amp either. Or a guitar, for that matter.
It's the realization that I shouldn't expect to find perfection that's allowed me to more fully enjoy each amp. I was always fighting with my Mark V because it couldn't fully do what the JP-2C can do. If I had gotten rid of my other amps, I would be fighting with the JP-2C.
If I wasn't the kind of person who cares about going fast and having great handling, I could buy a truck, be perfectly happy, and never want for another vehicle.
Unfortunately, that's not how I'm wired.
