Check the listing for details. Ai1 - Buffered Jack for Guitar & Bass. Condition: New. Listed at 44.00 USD. Transparent DIY Buffer Kit designed to work with every pickup and fit almost every instrument. The same technology as found in the Redeemer Install, all in one simple gold plated jack, making installation as easy as replacing the jack in most guitars. Many guitars, like the Les Paul and Telecaster for instance, have their jacks mounted inside a tunnel behind a mounting bezel. The Ai1 Redeemer simplifies installation on such guitars. Guitars that use thick panel jacks, or that have more complicated wiring (stereo outputs, or split mag/piezo set-ups) would need to use the Install version at the top of the page.​The Ai1 Redeemer is also great for adding a buffered output to volume pedals or other passive pedals, and has even been installed to add a buffered output on some mixers that we've modified.
