Line 6 Relay digital wireless systems take your guitar tone as seriously as you do. Their superior specs, exclusive technologies and modern designs deliver the tone you've always wanted to hear from a wireless system: yours. Exclusive VWT (Virtual Wire Transmission) technology ensures full-range frequency response, excellent transient response, and wide dynamic range - just like a high-quality guitar cable. Relay digital wireless systems produce full-range tones with 10Hz-20kHz frequency response, exceedingly low noise with up to 120dB dynamic range, and studio-quality resolution with 24-bit A/D conversion. (Comparably priced analog wireless systems offer 50Hz-15kHz frequency response and >90dB dynamic range. This wreaks havoc on your tone, especially if you use a high-gain amp.)
