    1. MUST HAVE DIY TOOLS! 5 Star Review

      Posted by on Jul 30, 2017

      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!

    4. Another great tool 5 Star Review

      Posted by on Apr 15, 2017

      I can't speak from experience in terms of having used other radius gauges because I haven't. That aside, I tested them against guitars with different radii and they're accurate to a T. I've also used them to confirm my first ever re-radius of a fingerboard along with the radius block. Awesome gauges.

    7. Good stuff 5 Star Review

      Posted by on Dec 15, 2015

      A nice set of gauges. They're thicker than they might appear (they're not flimsy) and the radius is clearly marked. Well worth the price, a must-have for any guitarist's toolbox.

      Better than the plastic ones I was previously using.

    9. Accurate and intuitive 5 Star Review

      The understring radius gauges are so far the best tool I've found for setting a guitar's action, in combination with something to measure the top and bottom strings to start you off. It takes a lot of tweaking, but if you set the strings so that each one is buzzing on the radius gauge, I don't think you'll find a more accurate setup. I'm talking very minute turns of your saddle height screws to get everything right. Although it takes time, this process is easier than measuring the inside strings against the frets, as well as being more accurate.
