The Royal Blue Overdrive offers a wide range of dirt from light overdrive to distortion, or, with the Distortion rolled all the way off, can serve as boost with EQ. Filtering is limited on the overdrive to provide transparent tone that you can tailor with the Treble and Bass knobs. One of the most valued attributes of an overdrive pedal is touch sensitivity. Like the best boutique amps, at low to moderate distortion levels, the Royal Blue OD 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. The Royal Blue can add this level of expressiveness to any clean or slightly overdriven amplifier.
