SO SO NICE!
I couldn't find black Bigsby 5/50/500 either so I went out and got chrome locking Grovers, and chrome vintage wire ABR reissue and I was golden. Obviously I painted it but also put in push-pull potentiometer for both humbuckers to get some Gretsch-like sounds.
I researched and spent enough but it was all fun and here are my theories and/or findings:
For tuning I found that you don't have to get a roller bridge (though it helps) but locking tuners is more key. Sperzel, like ESP/LTD likes to use is better than Grover locking tuners but both help.
To stop binding up of strings, lube the saddles and nut and you should be OK for moderate wang bar stuff but this thing will never get off doing Floyd and Kahler stuff lest you get a locking Bigsby nut and fine tuners (which is an expensive yet perfect aftermarket solution for those who are used to Floyds).
If you are ambitious, also solder ball ends to keep string intact on extreme pull ups, and at the same time, sand off rough solder and lube the cams.
And if you are hardcore, you can get roller cam for the Bigsby.
With some or all of these mods, you can start to approach the stability of a perfectly set up strat trem with roller nut and locking tuners, but still never get the true stability of any double locking tremolo where strings terminate at bridge somewhere, like on Kahler or Floyd, and terminate before the tuners at headstock, like Floyd locking nut or any Kahler old school locking nut just behind a regular nut. The Floyd nut is more stable than Kahler nut but both are more stable than the string terminating at the traditional tuner, whether it's locking or nut. The absolute key is to shorten string length on all places where it's not played like on Floyd, and lock it down without having string pass over nut or bridge like Gibson ABR type as on your guitar and mine.
If you have a guitar without above mods
and go Floyd-ish like any high energy live situation can bring on, even if just for a few seconds, you will easily pull guitar out of tune (check out 4:57 of example of overheated Bigsby work in below video). At this point, you grab another guitar for next song. Also, I love the sound of your band and your ESP with Bigsby should be a great addition.
