Double Helix Upgrade System

K&K Sound is proud to announce the launch of its first-ever magnetic soundhole pickup, the Double Helix. The Double Helix is a hum-cancelling, dual-coil pickup for steel-string acoustic guitars.

This Upgrade option provides a Double Helix pickup,a twin-channel Dual Channel Pro ST external preamp and a stereo cable so you can add it to your existing system.

The Double Helix pickup has two coils, so it is hum-cancelling. However, the Double Helix is unique because the second coil isn't just there to remove the noise, it actually allows you to dial in different coil combinations, resulting in different tone and phase settings. It's the first soundhole pickup that has both a built-in tone switch and a phase switch.

The phase switch allows you to adjust the phase of the pickup, so the Double Helix will can be used with any existing pickup already in the guitar. The phase switch allows you to ensure the Double Helix and any existing pickup in your guitar resonate in the same phase. Out of phase pickups provide a thinner, weaker sound.

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. In the GLOSS setting, the Double Helix provides 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. Both tone settings are hum cancelling.
