I've mounted a floyd-ish trem on my guitars which are/were equiped with a regular trem (2 point). Now I'm about to install a superVee trem system on my favorite axe.
difference in tone? Little to nothing
same with the kahler. its more metal, thus it gives you a bit more highs, more 'crunch' in the tone, but no lack of sustain. I blocked the trem once, cause I thought it would be good for the tone, but I didn't like it. the tone didn't change really a lot, neither did it give me/the guitar more sustain. it just made the trem useless.
I also mounted a full EBONY neck on the guitar (like maple/maple!) and that was awesome! super-tight, crunchy, agressive, jangly when played clean. its awesome
though if you'll have a maple/maple neck, it will be a bit less bright compared with ebony, ofcourse. And I'd recommend a canary neck + ebony board (or padouk), cause that combination sounds the same as maple, but it looks cooler, and feels so much better. I just don't like the feel of a finished neck! and if you're lucky, just like me, you'll have a flamed canary neck :hello2:
if you want to have a trem, I'd choose a kahler. less wood that needs to be chopped away, more ways to intonate and set it up, and its supereasy to lock it down, and the trem-arm doesn't get in the way, and the 'feel' is of a ToM!.
but if you want to go the 'floyd' route, I'd take the superVee, cause its easier to install, easier to use/tune/intonate, looks better (more sleek), better way to pop in the tremarm, and its a 1 on 1 replacement with a wilkie and a hipshot trem! thats why I was able to swap so many tremsystems on 1 guitar.
Though I myself want to wait a couple of months before the Crowe Bar is finally done. it will be, eventually, a double locking trem, with a system to lock the trem in place, like a fixed bridge, with you swivel the arm away.
