KSM Guitars has revolutionized bass bridges with the Foundation bass bridge. This bridge utilizes a patented ramp system that allows for precise adjustments and maximizes the transfer of string-to-body vibrations, giving the instrument exceptional brightness and clarity. Made out of Anodized 7075 aluminum, the bridge is extremely resistant to corrosion, as well as, extremely resonant. The bridge’s patented locking system locks all adjustments into place, allowing the bridge to maintain tonal integrity after extended use. Available in both 4- and 5-string styles, this bridge is a great replacement part, or, it is perfect as an OEM.
