A module that is unobtrusive, yet keeps the controls where you need them.
The D-TAR Wave-Length Volume & Tone Module puts its controls in your acoustic guitar's soundhole for easy access. With all controls at your fingertips, and the Wave-Length preamp (sold separately), residing at the guitar's endpin, there's no loss of tone or dampening of vibrations due to batteries and electronics attached to a side-mounted pre-amp assembly.
D-TAR - Duncan/Turner Acoustic Research
Seymour Duncan and Rick Turner are two legends who spent years working with musicians, perfecting their tone. Seymour founded his self-named company in 1978 which has become well-known for its wide variety of guitar and bass pickups used by just about every name player from Billie Joe Armstrong to Angus Young. Rick co-founded Alembic, was president of Gibson Labs West Coast R&D Division, co-founded Highlander Musical Audio making piezo acoustic guitar pickups for Lindsay Buckingham, Ry Cooder, David Lindley, and Andy Summers, and runs his own Renaissance Guitars. Now Seymour and Rick are working together to create innovative products for acoustic musicians. Their D-TAR motto: "With respect to acoustic tone."
