I recently bought a 2014 American Standard Strat that has a Vega-Trem bridge/tremolo installed. I'm not a trem guy at all; the rest of my Strat's are either blocked or decked. However, the Vega-Trem is easily the most fluid and reliable trem I ever played with and I figured I'd leave it for awhile, "it's good to have one guitar with a trem" thinking, etc. It's been a month or so and...I'm just not feeling it. This Strat is so good I'd just prefer it to be trem-less. My question is, I know that the 2008 and later American Standard's use this bridge assembly, which added bent steel saddles and a new block material: However I have also seen the American Professional series bridge assemblies that look to be pretty much the same thing, save for the pop in arm: Now since I don't use the tremolo the pop in arm does nothing for me. But are there any other changes to the Pro's block or something? Is it even compatible with older US Strat's? I'm just curious and can't find much about it. I assume most would say just get the direct replacement assembly (part #007-5091-049) and be done with it but I'm curious if the American Professional bridges offer anything different/better?
