v4 is a PCB based on the MayQueen circuit, designed to replicate the tones of the Red Special guitar heard on Queen albums. The circuit has been tweaked by Tonmann to provide tonal changes and includes a SAG control for added versatility. The pedal responds well to changes in guitar volume and works well with single coil pickups. For even more versatility, the addition of the Tone TwEQ 3 Band active EQ in series is recommended for boosted AC tones.
