Natural Tone Filter System

The Natural Tone Filter System is the world's first felt-based tone control solution designed specifically for condenser microphone pickups on acoustic and classical guitars.

Instead of EQ or digital processing, the filter physically shapes the microphone's sound — reducing harshness, taming feedback frequencies, and bringing out the warm, natural character of your instrument.

Designed as a companion to the NV Tone Swan microphone system. No batteries, no electronics — just pure acoustic tone control.

Included with all SWAN series microphone.
