Gotoh high quality machine heads for 5-string bass 4xL,1xR. RESOLITE. Chrome. Bass guitars have weighty machine heads and by their very nature have always suffered from “neck-dive”. With the advent of 5 and 6 string basses, this tendency became still more acute, making long sessions uncomfortable for the musician. The RES-O-LITE series was developed to solve this problem. By chiefly using the special alloy “duralumin”, excellent weight savings are achieved. By use of the Rock-Solid mechanism the GB350 transmits string movement more powerfully, whilst retaining tuning and giving a smooth winding experience.Gear ratio: 1:20Weight: 40,0 gram per piece, nut and washer included
