Need 3-post Thunderbird bridge help

    I just picked up a used Epi Thunderbird IV. I put new strings on, the gauge was different, so I had to adjust the action, and while I was doing that a bridge post bushing popped out. No problem, I glued it in and tapped it down tight with a mallet, but I don’t want to do this all over again. Would someone with a Thunderbird IV tuned E–G please do me a favor and measure the height from the body to the bridge at the three screw slots so I can have good ballpark measurements to start from? If you want to know I’m using a D’Addario XL 45–105 set.

    I do know you want to adjust the smaller screw closest to the neck slightly higher than the back 2 to keep the tension of the strings from pulling the anchors out.

    For ballpark numbers, I adjusted my son's Goth Thunderbird like this. 2 back posts have about 2 threads showing, and the front has 3. Hope that helps!

    ^Yes, do set the front a bit higher. You need to adjust height for you, other peoples measurements mean nothing.
