Mad Professor Royal Blue Overdrive Pedal

The Royal Blue Overdrive goes from light overdrive to distortion but it can also serve as a boost with the Distortion rolled off. Filtering is limited on the overdrive to provide transparent tone that you can tailor with the Treble and Bass knobs. Like the best boutique amps, the Royal Blue OD is very touch-sensitive and lets you determine the amount of breakup by how hard you strike the strings with your pick, and/or by adjusting the volume knob on your guitar, on any clean or slightly overdriven amplifier. For best results, do not use a buffered pedal before the Royal Blue OD.
