The Royal Blue overdrive is an extremely touch sensitive overdrive. It offers wide range of tones from light overdrive into distortion and at lowest Distortion knob setting works as an EQ. It can also be used to create tube amp-like crunchy  ‘strike hard for distortion’ effect. There is not much filtering on the overdrive, to provide transparent tone that you can tailor with both the Treble and Bass controls.

Mad Professor Royal Blue Overdrive Features

  • VOLUME: sets the overall output level of the pedal.
  • DISTORTION: controls distortion, for most dynamic response set where the amount of distortion is controllable with picking force.
  • TREBLE: a boost/cut “shelving” type equalizer that controls the amount of high end, operating  where the Presence control is on most amplifiers. Treble can be used to add shimmer to even bright amplifiers without interfering with typical treble boost of most amplifiers.
  • BASS: a boost/cut shelving type equalizer that controls the low end, just above resonance of a standard 4×12 cabinet. With both Bass and Treble turned up, you can get a scooped heavy tone, turn the knobs down for soft mid-boost tone.
  • Transparent Overdrive: The Royal Blue Overdrive is renowned for its transparency, preserving the natural characteristics of your guitar and amplifier. It enhances your tone without masking the instrument's inherent voice, allowing your playing style and guitar's unique personality to shine through.
  • Versatile Gain Range: From mild crunch to searing leads, the Royal Blue Overdrive offers a wide gain range that adapts to various musical styles and playing preferences. With the responsive gain control, you can fine-tune the level of saturation to match your desired sound.
  • Responsive Tone Controls: The pedal features highly responsive bass, middle, and treble controls that enable precise tone shaping. Whether you prefer warm and smooth tones or bright and cutting sounds, the Royal Blue Overdrive empowers you to dial in the perfect tone effortlessly.
  • Built to Last: Handmade in Finland using high-quality components, the Mad Professor Royal Blue Overdrive is built to withstand the demands of professional use. Its rugged construction ensures durability, making it a reliable companion for gigs, studio sessions, and touring.
  • True Bypass: The Royal Blue Overdrive employs true bypass switching, ensuring that your signal remains unaltered when the pedal is disengaged. This maintains the integrity of your guitar's tone without any signal degradation.
