Sunrise Pickups are handbuilt by Jim Kaufman in limited numbers, but this allows the finest attention to detail and craftsmanship. Each pickup has individually adjustable pole pieces to give you maximum control over string balance and tone. They also come with a transferable lifetime guarantee—no doubt because of their remarkably sturdy construction and high-quality internal components. Jim also builds preamp/buffer boxes to accompany the pickups. We strongly recommend using these even if you already have some sort of outboard preamp you're using.
All Sunrise pickup models start with the exact same award-winning pickup; the only difference between the different versions is the length and design of the connections. The S-1 includes only the pickup and an 8" connecting wire, so you should really only consider this version if you already have all your internal wiring in place, and you don't mind soldering.
