Timber-line is a piezo cable pickup coupled to an 18 volt, low-noise, high input impedance preamp with twice the dynamic range of 9-volt preamps.
The increased dynamic range and adjustable bass trim pot gives musicians a more natural and full sound. Timber-line is the perfect piezo pickup system for musicians who want a more complex signature from their acoustic guitar.

Feature	Benefit
Unitary full length pickup	Accommodates all string spacings and gets a more even response from the guitar’s top
Co-axial cable design	Can get a more complex signature sound of the guitar due to 360 degrees of vibrations along its length
High headroom	Allows for twice the dynamic range of a 9 V system, hard strumming, and reduces piezo “quackiness”
Dual source capability	Allows the user to combine with a mic, magnetic or soundboard transducer for greater complexity of signal
Easy to install	Installation intended for guitar builders and luthier-techs
Adjustable bass trim control	Simulates the air resonance of a typical acoustic guitar, warms up bottom end
Stereo buffer upgradable	Allows buffering a second signal to ensure proper impedance match
