RayRoss will maintain to his grave that this hardware is the most cost effective upgrade you could ever perform on a bass. You cannot achieve results like this with pickups, preamps, or strings. Some market success has provided tons of feedback and response from players all over the world. Enough at this point for for me to say this: RayRoss is not a bridge. It is a studio grade"pre-amp" and reference monitor for the bass, and it is MECHANICAL in nature. No plugs, cords, dials, etc..All the sound, instantly. No more dead spots. No more trouble hearing what you are playing, for you or anyone listening. Everything ELSE is a bridge.
