Is this something you've already done or something you're going to do (and that is a stock pic from the net)?
Personally, I hate that bridge/vibrato system with a passion. Hardcore Jaguar and Jazzmaster lovers will say that it can be set up to work fine but I beg to differ. I love Jaguars and Jazzmasters but simply won't own one because of those systems.It's an idea rolling around in my head, and yes, that's a stock pic I Googled.
That much is true for sure, but so does a Bigsby. Strat bridges just aren't subtle enough to get that nice shimmer. Bigsbys can be mounted in a non permanent way.To me they have a much smoother, less abrupt function than a Strat trem.
A roller bridge plus a Buzzstop should take care of most the issues.that tremolo needs something offset, a bolt on neck and some type of shim...
I've shimmed necks on Jags & Jazzes before, and it really helps lower the action. But remember that Gibsons have a few degrees of neck tiltback built in, so I believe this trem will work well on an SG.
I wouldn't use a Mastery brideg; too spendy & ugly, but would definitely consider some type of roller bridge.
Yes, I've also considered using a Maestro SG junior as a proof-of-concept build. If I could get a smokin' good deal on a recent Epi SG Special I might try that. Something with a wraparound bridge, no stop tail.
You'll have to buy a locking wrap around bridge or swap to a tune-o-matic. There won't be enough down pressure to keep the existing bridge where you want it. If you switch to a tune-o-matic you'll likely see the original post holes.
