To adjust the JTV-59 bridge
* Loosen the strings
* loosen the small allen screws
* now use a larger allen wrench and adjust the height of the bridge to taste. occasional retune the guitar to check, but always loosen the strings prior to adjusting the large height "bolts" under the bridge.

Upon achievement of desired bridge height reverse the procedure

* tighten the small allen screws
* retune the guitar
* and recheck intonation with a strobe meter
