The Boneshaker is a collaboration between the minds of the guys at Black Arts Toneworks and the effects powerhouse that is DOD. This pedal is a heavy distortion a fully sweepable parametric EQ that was specially designed for downtuned guitars and bass, but it works great in standard tuning as well. The depth control works in conjunction with the level to help manage low end and the EQ offers tons of flexibility in terms of tones and gain staging, since you can easily use the EQ to add gain centered around specific frequencies. If you need any sort of heavier gain, this is a great option. It really sounds great into a driven amp, helps push it into that nice thick roar. Please feel free to contact us with any questions!
