Wilkinson WVPC-SB 54mm (2-1/8 polegadas) Selas de Aço Inoxidável 6-Buracos Ponte de Tremolo para Violão com Bloco de Aço Sólido Completo para Importação Strat e Estilo Japonês Strat Violão Elétrico

Does not float but with locking tuners , this trem returns to zero very well .I'm happy with it .

The Trem bar doesn't stay, always fall down it doesn't hold

Turned out to be pretty nice. Comes with the 6 mounting screws, 3 springs, claw and the 2 screws for the claw. Bridge itself has pretty decent mass, I believe it's a steel block and baseplate. Most cheaper bridges use cheap pop metal and has very little mass for sustain. Mine is on a 3d printed guitar, and has plenty of sustain. The stainless saddles look good, and the way bar fits perfect with no play. Cheaper bridges also tend to fit lose and that makes use of it not as functional.

Solid well made tremolo. Like anything Wilkinson makes.

Wrong size hex wrench in box, so be careful or else you could round off the hex wrench or the inside of the grub screws. You might need to get a separate set of wrenches. I suspect the wrench in the box was metric, because my own wrench that ended up fitting was SAE in inch fractions ( might have been 1/64", but don't quote me on that). Some of the saddle heigh adjustment screws were a little tight at first, but loosened up by turning them back and forth a little bit with the correct size wrench, probably just tight machining tolerances. I might run some sandpaper or a file in the saddle grooves to address a little bit of string buzz that seems to be coming from the bridge, the saddles are all identical so my thicker strings might benefit from adjusting those slot width or groove angle a little bit.I bought these to replace some slightly grooved saddles on an Ibanez YY10 that had the bent steel type saddles (which comes with a Wilkinson bridge... I kept the original bridge, screws and springs but just replaced the saddles with these).Anyways, my situation is probably not typical since I didn't drop in the whole bridge, but just wanted to share my experience. I didn't realize at first that this doesn't appear to be the actual Wilkinson brand (just Wilkinson style), but since the Wilkinson branded saddles themselves are like $100 for a set, I figured I could make due with these, expecting that some adjustments would be beneficial to get things just right. And every guitar is probably different so my experience might not be typical.Anyways, good luck to everyone else with their projects !
