The Edge Pro features a novel set of saddles with integrated string locks, and string holders which do not require removing the ball end of the string at the bridge side. The saddles are topped with a metal "sound chip" designed to improve the sustain usually said to be lacking from guitars with double locking systems. The usual criticism of the Edge Pro is that it lacks the locking bridge studs found in the earlier Gotoh bridges, but that is easily remedied by exchanging the Edge Pro studs for those of the Edge or Lo-Pro. A seven-string version, the Edge Pro 7, was also produced.
