All my Modifed Olt Key Holes cracked——either the barrel or the plug. Bought this from a guy who worked for Olt for decades years ago. Got it out recently. Starting to like it again. What is sold as a Cut Down today is nothing like the old hard rubber tonal plug calls we ran. There is no hold, ring or rattle in an old Olt. What you put in is what comes out. The reeds are/were .014 thick and will last a long time. All the tunning was in the cut on the tone board ——- no reed trimming whatsoever. Once it is cut right, it never changes tone or sound—-just pop in a new reed when the cork dies or the reed splits on the end. The real deal had a molded ABS plastic barrel or horse hoof-derived hard rubber barrel——no wood, no hard cast acrylic. The sound is gruff; not crisp like an acrylic call. The thick reed is part of what makes the call. The tone board has to be hard rubber, not wood, not acrylic.
