Whether you like crunchy overdrive, a flat out mid scooped distortion or just a little dirt and more EQ the Sparkling Blue will deliver. Based on the Vintage Guv'nor circuit the Sparkling Blue emulates this vintage pedal and adds a little color of it's own. Whether you like the classic sound of the pedal or a slightly punchier fuller sound via the clipping switch the Sparkling Blue is sure to quench your thirst for crunchy goodness. The Sparkling Blue boasts controls that mirror that of an amplifier. You have a level control that controls the over all level of the effect. You also have the self explanatory treble, mids, bass and gain controls. There is also a toggle switch to toggle between original clipping of the circuit and an added clipping feature. The Sparkling Blue is true bypass and powered via a 2.1mm center negative power supply or a 9 volt battery.
