Designed for electric bass players, the Source Audio One Series Aftershock pedal elicits distortion and fuzz tones by means of 56-bit DSP architecture, 24-bit AD/DA converts, four easily accessible knobs, and lots of under-the-hood features. Drive, level, clean, and tone controls are offered, as is a three-position toggle switch which gives you three different voicing mode options right out of the box: Tube, Heavy, and Fuzz. The Tube engine provides a subtle, vintage-style overdrive tone with smooth breakup. Heavy mode, on the other hand, offers a more present and scooped tone with emphasis on the lows and highs of the signal. Lastly, the Aftershock's Fuzz setting gives you gritty, germanium-type fuzz tones.
These are just the effects provided out of the gate. Play around with the included Neuro Mobile App for iOS and Android, and you’ll be able to edit a whole host of parameters. Extensive parameter editing enables you to customize your own signature tones, and what's more, save them to different positions of the toggle switch. You can also load in tonal presets from the L.A. Lady Overdrive and Kingmaker Fuzz pedals; if you wanted to, you could run a bass distortion, an overdrive, and a fuzz box from different positions of the toggle switch—effectively giving you three stompboxes in one enclosure. With connections for MIDI control, expression control, and Hot Hand control (in which you use a proprietary ring-like device to modulate effect parameters straight from your picking hand), you can achieve even more real-time manipulation of effects.
Dual 1/4" input and output jacks allow for all sorts of stereo and mono routing possibilities. The architecture for this pedal also allows for parallel and hybrid/series distortion paths, all handled internally. For a dive into other features of the pedal, kindly delve into the features section. A 9 VDC power supply is included with the pedal.
Diverse Distortion Sounds: Choose from distortion modes such as Tube, Heavy, and Fuzz, or delve deeper into esoteric sounds cooked up in the Source Audio lab.
Compact Design: The durable, anodized-aluminum housing has a slim profile, a small footprint, and sturdy hardware that can withstand the rigors of the road.
Universal Bypass: True bypass or buffered bypass? The decision is yours. The Aftershock features high-quality signal relays for true bypass and transparent buffers for analog bypass.
Stacking: Stack two independent distortion circuits in series (or in parallel), all within the stompbox.
Dual 4-Band EQ + Low Cut: Two independent parametric EQs are included in the Aftershock, allowing for fine tone control. An optional low cut filter tightens up the low end for bass players.
Flexible Routing: The Aftershock is equally at home in a mono rig or a stereo rig. A variety of routing modes such as True Stereo, Cascade, Parallel, Dry Sidechain and External Loop allow the Aftershock to harness the true power of stereo signal chains. It also works like a traditional bass overdrive pedal.
Preset Saving: Save your favorite sound by pressing and holding the footswitch.
Neuro Technology: The Neuro App opens allows you to access extensive parameters, different effect types, and provides access to the Neuro Community, including free presets from artists and other users. The Neuro Hub can store up to 128 presets for the Aftershock, easily recalled with a MIDI controller. You can also download any effects for the L.A Lady Overdrive and Kingmaker Fuzz, and use them on the Aftershock.
Deep Control Set: Beyond the four knobs on the face of the Aftershock are many additional parameters. The Neuro App provides access to the inner workings of the distortion effects for advanced users who want to create their own signature sound.
Noise Gate: A built-in adjustable noise gate, accessible from the Neuro App, helps remove unwanted noise.
Clean Path: The clean signal can be mixed in with the effect as desired, perfect for bass players who want to hold down the rhythm section with a clean low end.
MIDI Control: All of the Aftershock's parameters can be accessed and controlled using MIDI via the Neuro Hub or USB. Class-compliant USB-MIDI allows the Aftershock to work as a plug-and-play device with recording software running on Mac and Windows, and the MIDI Learn feature makes control mapping simple.
Drive Knob: Controls the amount of gain into the distortion circuit, which sets the amount of distortion and sustain.
Level Knob: Controls the overall output level.
Clean Knob: Controls the amount of clean signal in the output.
Tone Knob: Controls the tone of the effect.
Effect Switch: Selects between the three basic fuzz effect types–Tube, Heavy, and Fuzz. You can also store your own presets into the pedal and access them through this switch.
Footswitch: Enables or bypasses the distortion.
USB: Connect to your computer (Mac or Windows) to the Aftershock's USB port using a standard mini-USB cable. The Aftershock is a class compliant USB device, meaning that it should be recognized by Mac and Windows computers automatically.
Control Input: The 3.5mm Control-Input port connects to external control devices such as the Dual Expression Pedal, Reflex Universal Expression Pedal, Neuro Hub, and Hot Hand Motion Controller. The latter facilitates the use of Hot Hand technology to control aspects of the pedal directly from a ring-like device worn around your finger.
1/4" I/O for Neuro App Data: In addition to using the Aftershock's dual, 1/4" instrument input and output jacks for stereo routing, you can use the 1/4" Input 2 and Output 2 jacks as data connections for the Neuro App. The ring contact on Input 2 acts as a data connection for the Neuro App, and you can connect it to your mobile device using a stereo TRS cable with a 1/4" termination point. Input 2 can also accept daisy-chained Neuro data from another Neuro-compatible pedal in the chain, provided that a TRS cable is used. The audio signal (if applicable) will be on the tip contact of the plug, and the Neuro App data will be on the ring contact. Output 2, on the other hand, can pass said data from the Aftershock to the next Source Audio effect in your signal chain. You can daisy-chain the Neuro App data regardless of whether Output 2 is configured to output audio or not. Connect Output 2 to the next device’s Neuro App Data input (usually Input 2) using a stereo TRS cable with a 1/4" termination. The audio signal (if applicable) will be on the tip contact of the plug, and the Neuro App data will be on the ring contact.
Parallel Processing Capabilities: A clever way to create interesting distorted tones is to split the guitar signal, run it through two independent pedals in parallel, and then combine the results. Often, one path will sport relatively low gain, while the other will go for a high-gain sound. This approach can combine high-gain power/sustain with low-gain clarity, definition, and articulation. Usually this approach requires a lot of hardware: two distortion pedals, a splitter, and a mixer. The Aftershock, however, can do it all internally. Each circuit has its own clean and drive level controls, which allow for very fine balancing between the two sounds. Two parallel processing routing options are available in the Neuro App: MONO IN STEREO PROCESS MONO OUT and MONO IN STEREO PROCESS STEREO OUT.
Series/Hybrid Processing Capabilities: By selecting the MONO IN/OUT WITH CASCADING CHANNELS routing option, and then bringing up the clean mix level on channel B, it’s possible to create a series/parallel hybrid sound.
LoRetain for Clear Low End: LoRetain is a technique used by Source Audio to maintain a solid low end even with high amounts of distortion. This is particularly useful for bass players or extended-scale guitar players (7-string and 8-string guitars) that need to maintain a strong fundamental while keeping high drive on the upper frequencies. LoRetain is available as a control independent of the parametric EQ and low cut filter.
Voice Control: Each circuit features a VOICE control that is a gradual timbre adjustment affecting the overall character of the sound. It generally affects the midrange in subtle ways, so a high VOICE setting will generally provide a midrange boost, whereas a low VOICE setting will provide a midrange cut. Many different sounds are available using the VOICE control, which can be controlled via the Neuro App.
Noise Gate: Distortion, fuzz, and overdrive effects introduce a lot of gain into the signal chain, and this gain amplifies not just the guitar signal, but also any noise present in the system, especially when the guitar is silent or playing at very low levels. To correct this problem, the Aftershock includes a built-in noise gate to help reduce noise and preserve the guitar signal. The noise gate consists of a traditional gain reduction circuit as well as a filter gate, which works by attenuating high noisy frequencies when necessary. By default, the noise gate is not active. The volume gate and filter gate can independently be enabled and configured using the Neuro App. The gate will automatically be linked in stereo modes or independently configured in stacking and parallel modes.
