    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!

    Another great tool

    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.

    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.
