Sorry if this is in the wrong forum i wasnt too sure where to put it. Ive just started college and in our spare time we are allowed to use all the facilities which includes the engineering labs. I want to make my self a new bridge for my 4 string yamaha rbx270. Im just wondering what things i should take into consideration when making the bridge, and what materials would be best suited for the job i quite like the look of this Would i be right in assuming that teh circular bits on teh top part of the bridge are what one uses to set string height? Move them close to the bottom of teh bass and the strings get higher, move them towards the head and the strings get lower????
