Agreed. Pinkerton = best Weezer album, in my view. And Pop and FAR better than many have given it credit.
The thing that I don't like, is that the band don't seem to take criticism well. Rattle ANd Hum took some hits and they pretty much avoicd the album, other than a few of the singles.
Why no "God Part II"? Why no "Hawkmoon 269"?
The same can be said for Pop. It took some critical lashes, undeservedly... and most of the tunes have not been heard from since. Sad, that.
I fear the same for the NLOTH songs. "...Boots..." might get played.... but other than that... I doubt that they will play those tunes again. Heck, they dumped "No Line...", "Breathe" and "Unknown Caller" halfway through the tour.
As for the mirror-ball guitar... your's came out great. And it sounds that you have the same issue that Edge did - the dang thing being so heavy!
I'd be interested to hear some clips or see/hear video snippets of the guitar. I wonder how, if any, the mirror tiles affect the guitar sound.
You should take it and show it to Dallas and/or The Edge. They might cringe, thinking the original has come back to find them.
