Great block, with only minor drawbacks, for certain applications.The trem hole, in my baseplate, was too small. (As another reviewer mentioned.) (I’m not a fan of the plastic insert, but I can live with it.) Instead of opening the hole, I sanded the trem arm down to 4.4mm. Now it fits perfectly. (The trem arm was cheaper than the bridge, hence my approach.)The 6 mounting holes were 1/4mm too far away from the nut. Nothing intonation couldn’t fix.It’s a major upgrade. The full brass block, is completely different from the thin zinc-alloy.It has more sustain. It’s easier to float than the light zinc block. Returns to tune more consistently. The tone is even more… well, everything. It’s brighter, warmer, fuller, and cleaner. It’s not as brittle, or trebely(?), as the zinc. It’s most notable, with no effects. More so unplugged.I’d certainly buy again.
