    These gauges are great! They’re made with quality materials, and they work just as you’d expect. A great buy at this price.

    Been wanting a set of these but couldn't justify as I had an old set (not the under string type) These are great for tweaking electric guitars with adjustable bridge saddles. Very happy with the Quality & Price

    High quality. Fair price. Needed to know the radius of my guitars to compare what I prefer.

    well cut pieces, no sharp edges or anything, thick enough to be sturdy but small enough to be accurate. very helpful tools!

    I am new to bass playing. It’s a bucket list thing. I own two new basses: A Squire Affinity PJ and A Squire Vintage Modified PJ. Neither bass went through the ‘FREE 55 point evaluation’. I had taken the 1st bass, a Squire Affinity PJ, to the local Sam Ash for a complete setup but I was told to play it as is by the guitar guru and then come back and tell him what I didn’t like and he’d adjust it. Albeit. I will NOT be feeding the pig any time soon. Which brings me to learning how to DIY the setup process and needing the proper tools, like these puppies right here: THE UNDER STRING RADIUS GAUGE FOR GUITAR AND BASS SETUP - SET OF 9 My 7.25 had a couple of laser boogers on it but nothing that interfered with the use and gotten rid of using modeler's files... These are GREAT for setting string height @ the bridge!
