How’s this for a cool idea? The Seymour Duncan Triple Shot is a replacement pickup ring which includes two switches built right in, so you can switch to different settings without even moving your picking hand away from the strings.
According to the Seymour Duncan website:
This “stealth” pickup switching device allows you to access series, parallel and split wirings with a standard humbucker. And it’s easy to install. Just solder your pickup leads to a small color-coded circuit board. That’s it. Push the two switches towards each other for standard series wiring; away from each other for parallel wiring; and both towards one coil (either one) to shut that coil off.
The ‘triple’ in the title refers to the additional 3 settings (front coil only, back coil only, and both coils in parallel) aside from the standard series mode.
The Triple Shot will work with any humbucker that has 4-conductor wiring – just make sure you accurately translate the colour codes, because different companies use different wire colours. Here’s a site where you can check the codes.
The Triple Shot doesn’t appear to be available yet, but bookmark this eBay search and check it every now and then to see when it starts appearing in eBay stores.
