An accessory for the Wave-Length Under-Saddle pickup system that lets you change batteries simply and quickly.

The D-TAR Load 'N Lock system works in conjunction with the D-Tar Wave-Length Under-Saddle acoustic guitar pickup system. Load 'N Lock makes changing your AA batteries easy to do. Simply unscrew the endpin collar, remove the old batteries, and pop in tnew ones. A quarter turn of the collar is all you need to lock them in place.

The D-TAR Wave-Length acoustic pickup system combines a thin, piezo transducer with an 18V, low-noise preamp. Eighteen volts translates to twice the headroom and dynamic range of a typical 9V system, so you can strum extra hard without experiencing the dreaded piezo "quack."

To get its 18V, the Wave-Length requires only 2 standard AA batteries. The secret is a proprietary voltage power booster. In addition, the Wave-Length's pre-amp has 2 adjustable trim pots-1 low-frequency shelving and 1 high-frequency shelving. The result is transparent amplification of the natural timbre of your acoustic guitar with minimal coloration.

The Wave-Length volume and tone module's controls are located in your acoustic guitar's soundhole for easy access. With all the controls at your fingertips, and the Wave-Length preamp itself 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.

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.

Comments about Dtar Load 'n Lock Wave Length Battery Accessory:

Love the sound of this pickup through at Fender Super 112. I rarely like the sound of an acoustic plugged in. I installed it on my Art & Luthurie Ami that has the spruce top. Does not sound like the quacks that other piezos can have.

When I installed it, it was malfunctioning and popping, but I got in touch with dtar and they sent me a new part no questions asked. I love good customer service! It is difficult to fasten down the excess piezo wire and if moved around, you may hear the wire hitting the inside of the guitar. Not an issue if you pay someone to install it :)

Love how easy it is to change the batteries! No brained to some, but I don't recommend you record plugged in, use mics.
