Spark Booster was announced at Musikmesse in Frankfurt earlier this year and is available in stores throughout the world. It is essentially 3 different boost pedals in one thanks to the mini toggle switch that allows you to select from either a Clean boost, Fat boost or Mid boost. I used my Taylor SB2-S guitar using the neck and bridge humbucker in my demo to show how this selection affects your tone. I first setup my Ceriatone Chupacabra in Plexi mode nice and clean to show how much the different modes push the amp into a little bit of overdrive, perfect for Andy Timmons style tones and then with a very light Overdrive setting on the amp to show how up to 26db of boost can create a smooth singing overdrive tone.

Here is some info from a recent press release:

Spark Booster rounds off TC Electronic’s immensely successful line of compact overdrive and distortion pedals, but that’s not all. It also represents the ultimate salute to TC Electronic’s legendary Booster + Line Driver & Distortion.

Spark Booster features 26 dB of boost, making it the perfect tool for enhancing existing sounds and highlighting solo or rhythm parts. For guitarists who are looking for tonal options, an active EQ consisting of a Bass and Treble knob provides precise tonal shaping, as well as extended lows and added top-end sparkle. A Gain knob allows for the addition of sweet saturation and compression, and a Mid-boost switch adds loads of mix-cutting clarity to sounds. Spark Booster is also true bypass to ensure maximum tonal integrity. With this balanced set of features, Spark Booster simply adds ‘that certain something’ without any unwanted tonal shaping. Spark Booster injects punch, body and warmth into pickups, drives amps to peak performance and adds life, grit and tone to guitar set-ups.
