Fourth version of the popular Charlie Brown overdrive effects pedal that is voiced to transform any good amp into a living, breathing replica of the original Marshall JTM45 tone that built an era, loaded with warm, rich character that makes a Stratocaster sing and a Les Paul scream. This version builds on the popularity of the V3 by keeping the same heart and soul while giving more flexibility and options. There are Volume, Drive, Bass, Mids, and Treble controls: the Volume control acts as a master volume would on the amplifier; the Drive knob controls the amount of dirt or overdrive in the path. With the gain below 50%, it is a low gain grit overdrive that even Hendrix would be proud to turn on. When user gets into the upper half of the gain control, he will find a new world of natural, crunchy bite that stands alone in the line of overdrives. New to this version are the Bass, Mids, and Treble controls that faithfully replicate a Marshall-style amplifier tone stack. All three of these controls act as a cut and boost, while at noon they are relatively flat. The right 6,3mm jack is the input, and the left is the output. This pedal requires standard 9V DC negative power, consumes less than 100mA, and measures 56 x 109 x 38 mm.
