I have had this guitar for several years now and hadn't realized that I didn't post a review. The stock pickups definitely did not sound bad, but I had a set of Lace Alumitone P90s already, so I put those in soon after I got the guitar.
This is a very comfortable guitar to play, with a slightly fuller neck profile and tall frets. I did need to smooth out some sharp fret ends and polish the frets as well; they were all pretty level, no noticeable fret noise or buzzes. The nut was a bit tall but playable - I've since sanded a bit of height from the bottom because the slots were done well. The neck has a very nice satin finish which I didn't feel the need to sand off. These offset bodies are always my favorite for playing either standing or seated, this one is no exception and it has a solid positive fit with the neck with good weight and balance. I still enjoy playing this guitar all the time.
Not sure if this is the same with the new models, but the pickguard is just a decal of sorts on a white 3 ply guard it seems. My pinky has worn the tortoise shell graphics right off from years of resting it there as I play. It doesn't bother me but I figured I should mention it.
I was very surprised by the overall quality for such an affordable guitar. I would say this is an incredible value for the price. I've played several hundred guitars and have played far worse brand new guitars from other makers in the same price range. Very much worse.
I will add that I've also since bought a Harley Benton TE90 FLT model from Thomann and it is equally impressive and possibly more so. The pickups are pretty mush spot on for my Filtertron taste. I would basically make the same assertion about the neck and fretwork as this JA model. Playable out of the box, but needed a bit more setup work, in my opinion. They just seem to build solid budget guitars.
