Maestro (by Gibson) Titan Boost. A boost pedal that offers a little more than other boost pedals do. The Tone and Level knobs allow you to control this as a standard boost. Dial in a tone and adjust the level to give the perfect amount of breakup and crunch for your specific guitar and amp setup. You also have a switch to bring in a high pass filter. When this switch is on, you have the High Pass Filter knob to give that extra tonal adjustment other pedals don't. This pedal has been gone over by an experienced electronics tech. The foot switch was found faulty and replaced with a new one. Pots all cleaned, and everything tested, all works as it should. This is one of the better sounding boost pedals I have found to date. Designed by Gibson, this pedal delivers, from bluesy breakups to driving crunches this pedal gives it all, and is ready to once again inspire. Pedal sold as shown, original box, battery, and manual not included.
