As noted above, it's worked out brilliantly for me. One thing is, I needed it for a six-string guitar where it hadn't bowed that much, so it was more a case of using it to hold things where they are. And it turned out there was already a screw in the bridge in the right place to start with, which made things easier.

And thanks to the present currency rate it's remarkably cheap from Stew-Mac Including postage it works out as £16.65. And now I'm on their mailing list so I get a catalogue every now and then, and it's mouth-watering stuff.

The thing that has impressed me is how much it's improved the sound of the guitar.

Myself, I prefer inches to metric. But then I was brought up that way.
