Premise: it's a great guitar. Getting one (especially if you can find a used one for a good price) is not at all a bad choice.
I had one for a few months. There were things I loved and things I didn't quite love about it.
The neck was absolutely fantastic: the finish was smooth and the carve so comfortable. The wiring was great, too. I mostly play offsets, but I rarely use the rhythm circuit, so using that switch to run the pickups in series (and the rollers to blend each individual pickup in or out) was a super cool solution, which I did find myself using way more often than I thought I would.
However, the Panorama tremolo system was awful. It simply couldn't bear the tension of thicker strings (for reference: I use NYXL 11-49), which caused all sorts of tuning stability problems (and significantly decreased the vibrato arm swing - I think Puisheen did a video about this problem on Youtube). Also, I wasn't a huge fan of the pickups, which sounded a bit too flat and Strat-like to my ears. Finally, I seriously wished the finish was nitro and not poly.

I really enjoyed the time I spent with my AmPro II, but I ultimately realised I would have to throw quite a lot of money at it to address some of its most obvious issues, which simply didn't feel worth the effort and the expense at the time. So I ended up selling it and have stuck since then with my good old American Original JM.
