Seymour Duncan's Stratocaster pickup, The '60s Surf for Stratocaster, one piece. Unused, 2010 model!! It's triple-packaged with the outer box, a logo-printed linen drawstring bag, and wrapping paper. The wrapping paper has never been opened. The serial number on the tag starts with 10, indicating it's a 2010 model. I bought too many of these when I was really into modifying guitars... The resistance of this individual pickup, as measured by Duncan, is 6.48k. This is slightly higher output than the catalog spec of 6.30k. Since 6.5k to 6.6k is common for the Surf, I think 6.4k is a standard value.
