I have two old Stimers pickups for sale.
one fits a D hole shape soundhole or a folk guitar with a round soundhole.
You don't see these around much. I'm selling it on Ebay for $375 but I'm offering it at $350 with free shipping (within US) here.
The second one is older.Would look really nice set up on a guitar.
Dimensions are 75 x 26 mm. $300 firm.
Send me a message if interested.
