This TC Electronic Spark Booster is more than just another run-of-the-guitar shop boost pedal. Where most boost pedals use a single volume control, this one boasts Gain, Level, Bass, and Treble, as well as a three-way Boost Characteristic Switch that allows players to boost the clean tones, add girth to the heavier ones, and punch up the mids for that sick solo. With an active 2-band EQ working independently of each other, mimicking a graphic EQ, you're given increased functionality with the ability to control each band with the precision necessary to find your tone. And for those of you with expansive, sprawling pedalboards, the Tone Bypass circuitry cuts it off entirely from the other pedals, preventing the potential for any additional, unwanted noise. The TC Electronic Spark Booster is an ingenious pedal that compliments any guitarist.
