Customer Feedback & Comments:

"Received the goods. Beautiful tool and workmanship. Thank you for your service". Miguel A., Puerto Rico.

“Thank you for the Nut Jig - It is perfect!. I also wanted to thank you for the Fretboard Slotting Jig and Fret Press, these are both excellent and work great. I have not been building guitars very long but your tools have helped enormously. There has been a marked improvement in the quality of my fretwork and nut shaping due to the accuracy and ease of use of your jigs. Oh, and the String Action Gauge is a very nifty little thing!”. Many thanks, Michael K., Cambridgeshire, UK.

“You make such great tools, and reasonably priced too. My friend who is a highly respected engineer commented on the excellent quality of my GMC tools and he has no interest in guitars at all! I'll be ordering your multiscale fret slotting jig next, as far as I can make out it seems be the only commercially available one in the world at the moment?". James P., Dorset, UK
