RAY ROBINSON STRAIGHT MUTE
Here's a nice example of a Ray Robinson straight mute.
Estimate it was made around the 1950's.They are widely used by commercial and studio players alike for their sound production and tuning. These are great soloist mutes also.
This example is in excellent condition - there is some flaking on the logo of course (cosmetic) and a little around the top of the mute which is also just cosmetics.
Mutes corks are in great condition also. This particular example came from a collection from a professional trumpet player who was playing at a National level.
