K&K Sound Double Helix Solo

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.

When we developed the Double Helix, the major requirement was that it should work both on its own and in combination with the Pure Pickup in a way that would enhance the final tone. The Double Helix features two switches, which are easily accessible even during play. One switch is for the phase, and the second switch is for tone.

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.
