Well, they told me it wouldn't fit...but I bought it anyway. What I have is Squire Std. with the 2pt trem (2-1/16 spacing). Just by looking at the original trem block vs the pix of the GF on their site...pretty close. I asked GF up front and was advised that it wouldn't fit (they don't make one to fit a 2pt trem)...and they were right, up to a point. Basically, the block mount screws and the string holes were a good fit. The trem arm hole was off by about 1/8" (just an eyeball measurement) in the 7 o'clock direction. It took me all of 10 minutes with a jeweler's file to open up the arm hole in the trem plate. Voila! The trem arm goes in nicely now. Sure, the hole in the trem plate is wonky looking...don't care. Still got some work to do. The new block is much thicker than the original. The body rout needs some relief cut in so that I can dive the bar all the way down. I may never fix that as I can't imagine myself ever wanting to have the strings flop about (it could happen. I'm still a 12yr old in a 60yr old body). It appears that I can get fully back to the deck on the lift though...won't need any clearance that direction. Did the big brass block improve sustain? Heck, I dunno. I just wanted one. I would note that the GF block countersunk mounting screws are smaller than the originals. The GF's look like they're 8-32...the originals are probably 5mm (somewhat larger). I don't think this makes much difference but I have to say that the GF threads appear to be off kilter just a bit (not exactly perp to the surface). Again, not a big deal...but noticeable. It all went together nicely after the mod. And...I'm happy with it. PS the string holes in the new block are not as deep as the originals (by design). This adds a little mass, etc., blah, blah, blah. Downside: you can't re-use your old strings, as this new hole depth requires more string length. Sigh...new set of strings right down the toilet.
