Volume, Tone, and Compression Multi-band compression has long been a secret of mastering rooms worldwide to unlock the warmth and natural dynamics of recorded instruments. The Element VTC’s all-discrete, Class A preamp leverages this studio elixir with a proprietary analog compressor that operates below 400Hz. The compressor is tuned to reflect the actual dynamics of the acoustic guitar, creating in live performance the superior warmth and natural balance of tone achieved in professional studio mastered sound. Includes soundhole mounted volume and treble tone controls.
