11403-01 The Classic Stack Jazz Bass is a vintage-voiced stack design that is a noiseless drop-in replacement for any 4-string Fender American Standard Jazz Bass. We captured that great Jazz Bass tone from the definitive ’60s era, in a noiseless pickup design. The Classic Stack Jazz Bass is one of our most popular pickups, and with good reason. It has everything a Jazz Bass pickup should: presence without being bitter, smooth response, and a classic low-end bump. It captures the same great tone as our Vintage Jazz Bass single-coil, but without the annoying 60-cycle hum. This bridge model is slightly overwound to make output balancing easier, for a perfect match with the Classic Stack Jazz Bass neck pickup. (NOTE: This bridge pickup is the slightly wider American-sized Jazz Bass version. If you have a Mexican Standard Jazz Bass, you will likely need to use two neck pickups, as the pickup slots are both neck-sized on that model.) Hand built in Santa Barbara, CA, the Classic Stack for Jazz Bass uses Alnico 5 rod magnets, Forbon flatwork, 4-conductor lead wire, and is vacuum wax potted for squeal-free operation.
