Pick Holder.

Pick holder inspired by the ones on Steve Vai's guitars.

The holder is modeled super thin, but its designed to fit the picks I use. (Dunlop John Petrucci Jazz 3) that are about 1.5mm thick.

Fits my Jem pretty well but I'm unsure of any other headstocks.

If you want it to hold any thinner picks, try stuffing 2mm foam in the cavity. I haven't tried it but that's what I thought I was going to have to do to begin with.
