Mad Professor Royal Blue Overdrive Custom
Overdrive
The Mad Professor Royal Blue Overdrive Custom uses the Bluebird modification to approach the drive section of the discontinued Bluebird Overdrive.
It has increased bass and slightly reduced mids for a warmer character, with Bass and Treble controls for further frequency shaping.
Use it to add body to a clean or lightly driven amp while controlling breakup through picking dynamics and guitar volume.
