[Fig. 3] [Fig. 3: Adjusting bridge height] Metal adjusters Higher *3 *3 Counterclockwise Clockwise Lower *3 Adjust to the same height. NOTICE • Before adjusting the bridge height, loosen the strings in order to relieve pressure on the adjusters and make it easier to rotate the adjusters. Rotating the adjusters with without reducing string tension can result in damage to the bridge or strings, etc. • When adjusting the bridge height, make sure that the height of both legs is kept the same. Increasing string tension on legs that are unequal in height can result in poor surface contact of the bridge's feet, causing inferior sound quality, noise, damage to the bridge, etc. (Fig. 3 *3). • The strings are tuned to the following pitches. The 1st string is tuned to G, the 2nd string to D, the 3rd string to A, and the 4th string to E. Use a piano, tuning fork, tuner, etc., and adjust the pitch of each string using the tuning pegs.
