I want to replace the standard jazz bass bridge with a high mass 4 string bridge. I have read that a lot of these replacement bridges have a higher string setup from the thicker bridge plate. Some speak of routing out the body to lower that action and some say they are shimming the neck higher. I don't want to do either of those solutions. So, I ask, which brand/model of high mass bridges, if any, offer the lowest string setup without any further modifications. I actually have a 32" scale URSA J bass. Also, any opinions on the high mass 4 string bass bridge from Rondo Music?
