The Wave-Length combines a slim, piezo sensor with an 18v, low-noise, high-input-impedance preamplifier, creating a system with double the dynamic range compared to typical 9volt systems. The 18V preamplifier operates with two "AA" batteries, providing more headroom for your signal, preventing distortion during vigorous playing.

The preamplifier features an input for a second source, such as a magnetic pickup or soundboard sensor. It includes two adjustable Trim pots, one for low and one for high frequencies, allowing you to perfect the bass and treble, optimizing the Wave-Length according to the size and shape of your instrument.

This enables you to amplify the natural timbre of your acoustic guitar with minimal coloring. It includes a 1/4" jack (6.35mm jack) and detailed installation instructions.
