1970 Gibson EB0 bass
Tune-o-matic bridge

This bass is fitted with a two-point tune-o-matic bridge with under-bridge string mute, and chrome bridge cover. The mute would soon be discontinued, as the upright bass sound it was supposerd to produce became less relevant to the 1970s bass player. To raise the mute the lever on the left of the image would be pulled left, pushing the felt strip on the right upwards.
