For sale, a silver and gold plated Irving Bush M2 mouthpiece, marked as blended with a 1C and affixed with transducer pickup, a la the Varitone, for electronics effects and direct amplification from the instrument without a mic! Amplifiers of this type were made famous by players like Clark Terry and Miles Davis and are making a comeback lately with the resurgence of computer based music. Extremely clean overall, some very minor signs of use that do not affect performance.
