Taylor EXPRESSION SYSTEM 2 Pickup Unit This is a Taylor Expression System 2 pickup unit. It's a Taylor pickup found in their high-end lines. I removed it after replacing the pickup on my guitar. The accessories are all shown in the photos. It's a pickup with a 2-tone volume (L.R.), treble, and bass control. I confirmed it powers on without any issues, but it's just the pickup unit. I recommend it for those who can mount it themselves or for repair technicians.
