K&K Double Helix Magnetic Soundhole Pickup

Elevate your acoustic guitar’s live and recorded sound with the K&K Double Helix—a premium hum-cancelling, dual-coil magnetic soundhole pickup engineered for steel-string acoustics. Designed by K&K Sound, a leader in natural acoustic amplification, the Double Helix delivers exceptional tone, versatility, and feedback resistance without compromising the instrument’s pure acoustic character.

Key Features:

• Hum-Cancelling Dual-Coil Design: Enjoy clean, noise-free performance even in high-gain or stage environments.
• Phase Switch: Seamlessly integrates with any existing pickups (e.g., under-saddle or other soundhole systems) for perfectly balanced, phase-coherent tone.
• Unique Tone Switch:
  • GLOSS Mode: Bright, articulate, and highly acoustic—adds shimmering highs and warm, detailed midrange for fingerstyle, recording, or ensemble play.
  • STEAM Mode: Fuller, more substantial output with enhanced presence and body—ideal for strumming, band settings, or when you need extra projection and drive.
• Easy Installation: Fits soundholes with a minimum diameter of ~3.5" (90mm). Includes endpin jack adapter for a clean, professional setup. Choose the External Adapter for no drill installation.
• Passive Operation: No batteries required—reliable, simple, and true to the acoustic spirit.
