As its name implies, the TonePros 7 is a seven-string bridge. It employs a Tune-o-matic design. It features intonation adjustment on the pickup side, Phillips-head saddle adjustment screws and pre-notched saddles. It has large posts with 84.5mm spacing and metric threads. It is built to match a 14" radius neck. The TonePros7 is solely a guitar bridge, meaning that it does not anchor the strings to the body itself; the APEX2 uses a string-through-body setup.
