Donner Boost Killer

In great condition, works perfectly. 

Often likened to the Xotic RC Booster, Donner’s Boost Killer pedal is arguably one of the most aggressive boost effects available. For a budget-friendly effects pedal, it loads plenty of heat, making it an attractive option. If you are looking to enter the world of boosters, the Boost Killer could be a great starting point. Even with its lightweight and compact enclosure, this pedal features a bit more generous controls than your standard booster design. It consists of Treble, Bass, and Volume controls along with a dominant Gain knob.
