Description

Edit description

Introducing the Source Audio AfterShock Bass Distortion, a pedal that packs a punch in the world of low-end crunch. This masterfully crafted device offers a range of distortion tones from smooth, natural overdrive to full-on fuzz attack, all designed to give your bass the power and personality it deserves.

The AfterShock comes with three potent engines: Tube, Heavy, and Fuzz. The Tube engine propels a powerful vintage tube overdrive with a smooth breakup and plenty of punch. The Heavy engine delivers an aggressive scooped sound, adding crisp highs and thundering lows. Unleash the Fuzz engine for intense germanium fuzz tones, offering plenty of bottom and grit.

The pedal not only provides diversity in sound but also boasts an elegant, powerful control panel that lets you finely sculpt your signature bass tones. The Clean knob, a dry/wet blender, allows you to mix in just enough clean signal to maintain a solid low end without compromising the pedal's growl.

But that's not all. The AfterShock is compatible with the Neuro Desktop Editor and Mobile App, giving you access to extended EQ, stereo routing options, and Source Audio’s free library of 40+ overdrive, fuzz, and distortion algorithms for bass and guitar. This pedal isn't just a device, it's a gateway to a world of tones waiting to be explored.

Key Features:

3 Distinct Fuzz Engines: Tube, Heavy, and Fuzz
Dual Drive Engines: Stack any combination of drive engines in series or parallel
Stereo Input and Output Jacks: Distort upstream stereo signals or split a mono signal to dual outputs
Universal Bypass: Select either analog buffered or relay-based True Bypass
Preset Mode: Save a different preset to each of the 3 switch positions
External Control Input: Compatible with Source Audio expression pedals, the Source Audio Tap Tempo switch, and the Hot Hand 3
Neuro Mobile App: Access to extended EQ, stereo routing options, and a library of 40+ overdrive, fuzz, and distortion algorithms.

The only bass overdrive/distortion/fuzz pedal you'll probably ever need!

A great pedal right out of the box, but infinitely tweakable parameters with the Neuro App to get the exact sounds you need. A great option if you can't decide what dirt pedals to get for your bass. You can also download various presets uploaded by other users on the app cloud. Can't say enough good things about this.

The last bass distortion/fuzz pedal you will ever need

I have only begun to scratch the surface of this pedal. I haven't even downloaded any custom configs. But I was able to dial in several awesome fuzz/muff sounds within just a few seconds of plugging it into my board. It has replaced every other distortion/fuzz pedal on my bass pedalboard. I will update my review once I have a chance to dive deeper into the guts of this amazing pedal.
