Seymour Duncan Acoustic Guitar Pickup - Woody HC - Mint - $38 (Ypsilanti, MI)
Mail order cost is $49.99 - Be smart and buy mine for $40 postpaid.
Here is a mint (used twice, then back into original packaging) 'Woody' hum cancelling acoustic guitar pickup. Fits snuggly in the sound hole of most acoustic guitars, and may be easily removed again without harming the guitar. Includes an integrated 14-foot cable with 1/4-in male end to plug directly into your amplifier.
This is a passive, magnetic pickup that works only with steel string guitars. Will NOT work with nylon string guitars such as classicals.
This thing works amazingly well, but soon after buying the Woody, my guitar had to go to the shop for a repair. While in the shop I had them install a pickup, so I no longer need the Woody. My loss is your gain! This one is the Hum Cancelling (HC) model SA-3HC ... very cool!
