Fuzz effects guitar pedal that was developed from JHS well-received Colour Box pedal, inspired by a piercing guitar tone came through the speakers on the Beatles "Revolution 1" in 1968. This model is more streamlined for the one basic application of a dirt box. The controls are Master, Pre, Tilt, and Hi Pass. "Master" is the classic volume control that controls the overall output. "Pre" works as a drive or fuzz control like turning up the pre-volume on a preamp to send it in to overdrive. As reaching 75% and above, the fuzz will begin to gate out as user picks the strings harder when playing, it is very responsive to the input signal and touch. The "Tilt" control acts as an active tone control that is flat when the knob is at 50%. When turned to the left, the Tilt control boosts bass and simultaneously cuts treble. When turned to the right, it boosts treble and cuts bass. This allows for some very unique and usable adjustments to the overall feel of the pedal. The "Hi-Pass" toggle switch lets user activate from two different frequencies located on the side of the pedal, 200Hz and 750Hz. These settings let only the high band frequencies above them pass, and this allows for some amazing tone shaping possibilities. This pedal excels at Direct-In fuzz tones, but it truly covers more ground than user would first imagine. From subtle tube-like overdrive to classic rock distortion and all the way to spitting fuzz, it is much more than a one-trick pony.
