Well I received my bridge today. Quick rundown:
1. It is easy to install. There is none of the headache-inducing counterbalancing that's involved with the AVRI bridge.
2. It immediately made the guitar play better, and subtle-ly made it sound better .
3. The Jazzmaster character is still all there, just better.
4. The guitar now feels a lot more stable.
5. The tremolo still works and sounds fine, and returns to pitch just as well, if not better than stock.
Is it worth $165? That's a personal thing. I think its cost is justified, given the tooling and materials that go into its production. When you consider how much other replacement options cost (Mustang saddles, other alternative saddles, buzzstop, tune-o-matic installation, etc.) and then see how they don't really solve all of the issues, the Mastery I think is clearly a better option.
I play .11 gauge strings and don't have a super heavy attack, so I've never had too many issues with the stock bridge (at least strings popping off, or the bridge lowering). But I did hate how it was impossible to get really low action without having the strings hit the back of the bridge or the intonation screws getting in the way (yes I know they can be cut, and I had to do that on the G string's screw to get a decent setup). But the Mastery nullifies this issue completely and now I can set up the guitar up perfectly.
If you have a Jaguar or Jazzmaster, I highly recommend this product. The only downfall that it is rather pricey.
Now onto the audio comparisons...



I ran my guitar into a Firepod, which went into my iMac. I used ghetto-tastic Garage Band (Apples, ugh, I know) and Guitar Rig 3 plugin. The settings I used were as above.
These files will be available for a week as of January 4. If someone wants to host them elsewhere, that'd be great.
