Fast Track 1 and siblings feature punchy sound Highlights mid-range to low end sound when used with crunch sound. Shares parallel coils and twin blades just like Fast Track 1. Therefore, there is no need to adjust the pole piece or magnetic force. We originally designed a rear pickup like adding a Cruiser and Fast Trac1k, but if you use a humbucker in the rear, you can use it as a front pickup. The Chopper sound is a combination of a single coil and a full size humbucker that is stronger than a single, and clearer than a humbucker. It is a great choice for making tone, increasing power in Strat bridge position, two Fast Track 1 pickups, or Fast Track 1 (neck) and Cruiser (DP187, Middle) It will be a part of the set.
