One of a kind Indian warrior heads and a zombie buffalo tails guitar knobs. These are real head turners. They fit a 6 mm split knurled potentiometer post. I can also make them fit a 1/4" smooth shaft with a set screw. Just leave me a message. I hand make my Knobs here in the USA. I ship the same day. They stand 3/4" high and are 3/4" at their widest point. Please check my feedback and buy with confidence.
