I wanted a new neck pick up form Revelation Rjt-60. So I bought this, cause it had good review and It's cheap.
4/5 in sound because, some times it feels to dark for me, though those poles are adjustable, so I just have to adjust them.
No problems installing it, and build quality seems ok. Only con I see is that cover is not removable (at least I don't know how), as this is first P-90 pick up I have ever bought, maybe it standard for covers to not be removable.
All in all, I'm happy with this purchase!
