Vox · pedal

The Vox CT-03BT Cooltron Brit Boost is a battery-powered boost pedal built around Cooltron technology, running a real 12AU7 preamp tube at safe low voltages to preserve authentic tube dynamics and harmonics without external power. Controls include a Treble Boost/Full Range Boost switch, Gain, Tone, and Volume, with true bypass switching. Treble Boost mode emphasizes upper-midrange and treble frequencies for a classic British chime, while Full Range Boost adds low-mid and bottom-end content, useful for pushing an already-driven amp into heavier overdrive.
