I don't really know J Mascis beyond a single song but I couldn't say no to the sparkle blue body! I am in the UK so this cost me a staggering £1,219. That's the most I've ever paid for a telecaster but luckily I have no regrets. The neck is road worn which I normally wouldn't consider as I don't like the look of fake wear and the logic of ageing. However, I have to admit it's a great feeling neck - very smooth and a profile that's on the thinner side. It apparently has jumbo frets but they feel more like medium jumbos to me. Out of the box, the neck relief is .010 inches at the 8th fret. String height over the 12th is .070 on the low E and .060 on the high e. Measurements are a little higher than what I'd like but I wouldn't have noticed. The guitar plays very smoothly probably due to the neck and frets. The only issue is that the nut hasn't been cut well for the A and D strings. They're either too wide or not seated properly. I'll fix this myself later. All metal hardware and the mirror pickguard are aged too. Only the body is in "new" condition. As for the top loader, I've never owned one and was eager to try it. The result: I can't tell a difference between top-loading and string-though. It feels and sounds the same to me. I've read online that top loaders make the strings feel looser but there's no way I could pick this out in a blind test I really like the pick-ups especially the bridge. Tight bass and bright but not sharp on the highs. There's a lot of presence and upper mids to it. The only mod I'll do to this is replacing the mirror pickguard with something more traditional. (Any suggestions? I was thinking just a white or parchment 3 ply). Photos are hard to do justice to the blue sparkle as they all come out darker. The first photo is the closest to what it's like despite being an out of focus image. The blue is lighter and more vivid with a slight turquoise hue.
