K&K Double Helix / Pure Mini Combination System Acoustic Guitar Pickup

The Double Helix is a hum-cancelling, dual-coil soundhole pickup for steel-string acoustic guitars. It features a phase switch and a unique tone switch that allows players to easily change from a bright “GLOSS” setting to a more substantial “STEAM” setting.

The phase switch allows the player to adjust the phase of the pickup, so the Double Helix will harmonize with any existing pickup already in the guitar. The tone switch allows the player to choose from two settings: GLOSS, a fine and bright tone that sounds very acoustic, and STEAM, a more substantial and louder tone generally associated with soundhole pickups. Both tone settings are hum cancelling.

In the GLOSS setting, the Double Helix enhances the Pure Pickup’s tone with a light “shimmer” in the high end and a beautiful warm midrange. This combination features a “compression-like” tone that rivals studio recordings. The STEAM setting provides a much more substantial tone, louder, bigger and with superb feedback rejection. It is great if you need to bring the guitar up front in a mix.
