Patent ID: 8222503

Claim:
A sound reverberator device for detachable connection to the strings of a string musical instrument having strings tensioned over a bridge piece connected to a top wall of the sound box of said instrument, said reverberator comprising a housing open at a front end thereof, two or more metal springs disposed side-by-side in said housing and secured at a rear end to a spring support, a metallic attachment member secured to a free end of said spring, said attachment member has string engaging means for engaging a predetermined number of said strings in association with respective ones of said springs, said attachment member further having a bridge abutment portion for contact with said bridge piece, and means to tension said spring with said attachment member connected to said strings whereby vibrations imparted to said strings will be transmitted to said bridge piece and said associated spring; said spring being vibrated by said associated string and transmits its vibrations to said sound box through said bridge piece whereby to modify the tonality of the sound generated by said sound box as a result of setting the strings in vibration, and a sound damping pad displaceably supported from a non-sound damping position to a progressively sound damping position, said sound damping pad being spaced above said one or more metal springs and displaceable against a biasing sloped ramp to progressively push said damping pad against said metal springs to produce a progressive damping sound when said strings are vibrated to transmit vigration into said springs.
