I acquired up these pickups in September of 2008 and they have market value of $100.00. They are 1960's vintage Goldfoil guitar pickups similar to those used by Ry Cooder on his guitar. This was Teisco's version of the famous DeArmond Gold Foil pickups used on many Harmony guitars of the 1960's.
These were pulled as a working matched set from a Melody branded Teisco guitar with other issues. I marked the N and B on the backs to track their original position on the guitar. The neck pickup measured 5.49K ohms and bridge pickup measured 5.43K ohms. The lead wires are over 8 inches long on both of the pickups.
The most popular way of using these pickups is the "CooderCaster", a custom guitar originally built for Ry Cooder. A lapsteel bridge pickup and the old Teisco Del Ray neck pickup is mounted to a Fender Stratocaster.
Here are some examples of guitars modified with the addition of a Teisco Goldfoil.
I have about 3 more sets of these pickups so if you're looking for a set, send me an email.
