It's baby easy to use this pedal. Four knobs: 6-way sweep control range selector, Response, Sensitivity and Q controls. Just fiddle around with it and you can get an infinity of tones.
There certainly is enough tonal emphasis oozing from this pedal that it can act as a mild Overdrive at the very least and without added Drive pedals. The Nitro creates that element that is beyond what already exists.
Works well at both lower gain and higher gain settings, with an even wider array of tonal possibilities as you tweak the pedal's presence and bass responses, as well as your guitar's volume. You can achieve classic tones of the 70s, but it still sounds very modern.
