Carl Martin · pedal
The Carl Martin Headroom is a purely analog real spring reverb pedal featuring two independent channels, each with Tone and Level controls for adjusting reverb depth and character independently. Uses double-mounted springs to minimize stage feedback during live performance. Remote jacks enable external bypass and channel select switching. Runs on PP3 9V battery or standard 9V power adaptor. Danish boutique construction. Delivers authentic spring reverb character suited to surf, blues, country, rockabilly, and vintage-voiced guitar styles.
