Since this is a fairly new item I thought I would share some observations. I replaced a stock fender bridge with the new wilky vintage, partly just to try and also because it is an easy drop in, and like the pop-in arm feature. What a fantastic deal! You can get these new with a steel block for 40 bucks. My only concern was that it might be lower quality because the price is so low. Not an issue-this is a great bridge. The design is very good; it has a nice steel block that is full depth, full size. It is painted lightly black, no thick epoxy or anything. The plate is well-machined and polished, and it has the edge where it pivots angled across the screw holes like on the callaham, so it rocks smoothly and has good return. The saddles are nice, no burrs or plating problems, real smooth and look vintage. screws are correct length and operate perfectly for both action and intonation , and the holes all align perfectly on a 6 screw mount. Here is my favorite part-the arm is full vintage size and bend, and has the pop in design with set screw like the vsv. The only odd thing is the mounting screws are indeed large headed, and are a touch longer than fender sized screws. I luckily had a set of the callaham hardended mounting screws so I used those, which have a nicer (more beveled) head than even the fender ones. The springs that come with the wilky are sort of copper/brassy colored ones, which looks a little cheap, (don't know if it is good or bad)but I just left on the claw and springs from the fender bridge anyway. The sound is excellent, regular old fender bridge sound, no big change as far as I can tell without being able to A/B back and forth. If anything the wilky has a bit fatter low end. Very smooth highs, excellent with overdrive tones. The trem action is better, feels very smooth and even, and the arm feels great and stays where you put it. The best part is the tuning stability- I can use the bar like crazy and it really stays in tune (with nut lubed and strings stretched). I don't know if it is the plate edge, the staggered string holes, or the deep drill, but overall the tuning is better than the fender bridge. Lastly, the little closer string spacing keeps the E's on the fretboard, without drastically changing the feel from stock, and the bridge looks like a good old vintage trem. I really love it. I prefer it to the callaham bridge even if they were the same price, just swap the mounting screws for callaham or fender ones, and the springs, and you still come out way ahead cost-wise. This might be a drag for guys making expensive vintage type trems, because it really does what you want for less coin, and the quality is really excellent.
