Designed in conjunction with indie pedal builder Analog Man, the MXR Duke of Tone is based on the Prince of Tone Overdrive, the single-channel version of the King of Tone Overdrive. Analog Mike personally tested and matched the various thru-hole components to the King of Tone, ensuring that sweet sonic seasoning stays in the line of succession: a warm-yet-clear-and-open sound that allows all of the nuances of your signal chain to come through, from your individual guitar strings to the dynamics of your amps tubes. Volume, Drive, and Tone knobs cover all your basic tweaks while the Boost/OD/Dist switch allows you to set the overall attitude of the pedals output. Boost mode gives you a clean-yet-vigorous bump, OD mode adds a touch of grit and compression, and Distortion mode adds a touch more of each. In all modes, your rig still sounds like your rig. True hardwire bypass. Cannot be powered by a battery. Powered by 9 volt AC adaptor (ECB003) - not supplied.
