Can't say I agree with Andy on the price issue. I have sperzels on 3 guitars and I will have them on more, and I definitely wouldn't recommend anything else ( have tried others, but have always swapped them for Sperzels). It is well known that Sperzels offer what is arguably the best tuning stability on the market, so 60 quid is well worth paying for them. They fit beautifully, they're really solid, they look nice, and they make a massive improvement to your guitar.

These are undoubtedly fine components, and also look very pretty on your guitar (I got the satin chrome ones, mmm) but let's face it they aren't cheap! <br/>Staggered tuning post height is a neat idea, and these lil bad-boys have obviously had some thought put into their conception. String changes are quick and easy, and strings will stay in tune. period. <br/>BUT...grovers are also great machineheads, and whereas they may not look as classy, dare I say it, a little clumsy, but they're far more affordable, and boast 16:1 gear ratio, compared to sperzel's 12:1. That's some difference in fine-tuning ability! But I'm being anal here. If you have a fixed bridge guitar, there's not really owt between them. <br/>Only 1 problem. These cost sh*tloads.
