For the true fan, we have a limited number of harmonicas used by Zack in actual Smooth Hound Smith performances. Condition of each varies, as many have busted reeds and some minor scratches, but all were used in multiple gigs all over the US and/or abroad. It is not recommended that you play them (that'd be kinda gross), however they make a nice keepsake. Each comes with a signed certificate of authenticity.
