100/200 Series ES Under-Saddle Transducer
Inspired by our Expression System technology, the Expression System Transducer, or ES-T™, is a single-source, under-saddle transducer with individual elements for each string. (The ES-T was originally called the ES Element, but the name was changed to avoid confusion with another product.) The ES-T has an onboard preamp and the same active controls found on the full Expression System. Featuring a custom-voiced EQ and dynamic response, the system is powered by a 9-volt battery, with a battery life LED power indicator (which is lit when the battery is being used). The pickup also has a Phase switch for feedback control, which is located on the preamp board inside the soundhole.

Nylon Series / Fishman™ Prefix Pro®
This system features Fishman's Acoustic Matrix transducer pickup and a compact, side-mounted pre-amp with a flip-top 9-volt battery compartment. Additional tone controls allow you to adjust bass, treble, and mids. Brilliance controls and a notch filter add even more tone-shaping capabilities and feedback control.
Available on: NS32ce, NS34ce, NS42ce, and NS44ce

Nylon Series / Fishman™ Prefix Pro® Blend
Featuring a side-mounted control unit, this system combines a Fishman Matrix transducer with a miniature electret-condenser microphone on the inside of the guitar body (mounted on the underside of the control unit). There's also a small Trim Control that adjusts the volume of the microphone. Shelving-style Bass, Treble, and a semi-parametric Contour EQ enable tone-shaping, while a Phase switch and adjustable Notch filter help eliminate feedback.
Available on: NS52ce, NS54ce, NS62ce, and NS64ce, NS72ce, and NS74ce

Doyle Dykes Signature Model
The Doyle Dykes Signature Model is available with either the Expression System or custom electronics, designed by L.R. Baggs exclusively for the DDSM. Both pickups capture Doyle's signature sound and provide the responsiveness and articulation required for fingerstyle playing.
