I may be unlucky, but my guitar has a series of issues. It came with loose pots. The trem was fine for a the first few weeks, but when I changed strings I noticed that one of the Floyd posts was very loose. Ever since then it's been impossible to get it to return to level properly and I just had to block it off. Neck is great though.
Although it sounds great, I feel like it could be 200-300€ cheaper for the quality, and I probably won't be buying another Jackson any time soon.
