Source Audio One Series Aftershock Bass Distortion Pedal

The AfterShock is anything but clean with three separate tube, heavy and fuzz distortion engines, with four controls to sculpt your perfect dirty bass tone.

Get down and dirty with the AfterShock Bass Distortion. On its own the AfterShock features three massive bass distortion engines, but connect the pedal to the Neuro Mobile App (a free download for iOS and Android) and feast upon a massive collection of additional overdrive, fuzz and distortion tones. Further edit each engine with the Neuro's parametric EQ, stereo routing options, and internal stacking capabilities.

Out of the box, the AfterShock Bass Distortion packs 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.


- 3 Distinct Fuzz Engines.
- Stereo Input and Output Jacks: Distort upstream stereo signals, split a mono signal to dual outputs, or use the additional in and out as an external effects loop.
- Stackable Fuzz and Drive Engines: Dual fuzz/drive engines and stereo read more inputs and outputs make it possible (via the Neuro App) to stack any combination of drives in either series or parallel as well as split the signal and send a separate drive engine to each of the pedal's outputs.

- Universal Bypass: Select either analog buffered or relay based True Bypass.
- External Control: Compatible with Source Audio expression pedals, the Source Audio Tap Tempo switch (which also acts as an external switching mechanism), and the Hot Hand 3 Universal Wireless Effects Controller.

I got this pedal a while back and have thoroughly enjoyed it. It is on my main pedal board and goes to every gig I do. You can dial in any kind of overdrive or distortion with this amazing pedal. from Tube warmth to all-out metal mayhem. It is built really solid and after all I've put it through it still looks as good as the day it arrived.
