I had an old Pencrest acoustic guitar (JC penny catalog garbage?) that I put a standard strat single coil in the soundhole. I used some curtain hanging hardware for the pickup mount. The action was so bad on it I could only use it for slide. I just ran the wires to a combo jack/endpin. That guitar was delta blues all the way! It was so bad it was good! Considering what garbage all the old delta players played it fit right in.
