Used Source Audio Aftershock Bass Distortion, very good condition, includes original box and power supply (UK). No obvious marks. Fully tested.

Get down and dirty with the AfterShock Bass Distortion. Out of the box, this stereo pedal delivers three bass overdrive engines that span the gamut of low-end crunch, from smooth and natural overdrive to full-on fuzz attack. The Tube engine belts out a subtle, but powerful vintage tube overdrive with a smooth breakup and plenty of punch. Heavy creates an aggressive scooped sound with ample highs and thundering lows. The Fuzz engine offers intense germanium fuzz tones with loads of bottom and mucho grit. The Aftershock’s simple, yet powerful control panel provides the tools to finely sculpt the perfect bass tone. The Clean knob lets you to mix in just enough clean signal to maintain a rock-solid low-end without compromising the pedal’s SONIC GROWL. Adjust the onboard Tone control and find that thunderous sweet spot for any bass/amp combination.
