With 12 readily accessible delays and 12 more available by means of a corresponding app, the One Series Nemesis is a versatile delay pedal from Source Audio. The stompbox offers ten onboard knobs and switches, a host of expression-pedal possibilities, Source Audio’s proprietary Hot Hand control, and various I/O paths—including mono, stereo, mono to stereo, mono with an effects loop, and more.
Slapbacks, reverse echoes, Echoplex emulations, and more are made possible via the pedal’s 56-bit DSP engine, while industry-standard 24-bit conversion at the AD and DA stages preserves the integrity of your signal path. A tap tempo footswitch and corresponding subdivision toggle allow you to time yourself to the music on stage, while a soft-bypass mode is useful for implementing the organic cessation of delay tails, rather than curtailing your echoes abruptly. True bypass and buffered bypass are also provided.
As the pedal sports the ability to save up to eight presets at any one time, you can easily access a plethora of differing delays during a gig. 128 presets, controllable via MIDI, make this pedal suitable for use in sophisticated live pedalboard setups, as well as in a studio environment.
Connect the Nemesis to the Neuro Mobile App for iOS and Android devices, and you'll be able to access a panoply of under-the-hood pedal parameters, download presets from peers, and share your own delays. You can achieve Neuro App control over the pedal with an included 1/4" to 3.5mm TRS cable. As this pedal boasts a rich set of features, you may want to peruse the feature section for an in-depth look at the pedal’s array of attributes. Note that a 9 VDC power supply is included with the Nemesis.
Key Features at a Glance
The Nemesis features a 56-bit signal path with a 24-bit delay line for immaculately clean repeats.
The Nemesis is equally at home in a mono rig or a stereo rig. Every delay effect engine works in stereo multi-tap mode, and a variety of routing modes such as Mono-to-Mono, Mono-to-Stereo, and External Loop allow the Nemesis to harness the power of true-stereo signal chains.
Every Nemesis delay engine comes ready to go with both single and dual delay modes. Some delay engines make use of the Nemesis’ five-tap architecture to create fascinating multi-tap delays and rhythmic patterns.
The durable, anodized-aluminum housing with its slim profile and small footprint is built for the rigors of the road.
True bypass, buffered bypass, or soft bypass with delay trails? The decision is yours. The Nemesis features signal relays for true bypass and transparent buffers for analog bypass, as well as a soft bypass mode for preserving delay trails or complex stereo signal routing during bypass.
Save your favorite sounds with the touch of a button. 8 presets can be stored and recalled using the hardware controls, and a total of 128 presets can be saved internally and recalled using a MIDI controller.
Beyond its six control knobs lie many additional editable parameters. The Neuro App provides access to the inner workings of the delay effect for advanced users who want to create their own signature sounds.
The Neuro App for iOS and Android offers a powerful extension to the pedal’s basic functionality. Access the full set of editable parameters and save presets on your mobile device. Edit and share your favorite sounds with the Neuro Community directly from the App.
Configure external-loop mode to insert external effects in the delay line of the Nemesis, making them part of a feedback loop.
The Nemesis' parameters can be accessed and controlled using MIDI via the Neuro Hub or USB. Class compliant USB-MIDI allows the Nemesis to work as a plug-and-play device with recording software running on Mac and Windows. The Nemesis can also sync to your DAW or other MIDI devices using MIDI clock.
The Tap Footswitch allows users to directly set the delay time, with optional beat subdivisions.
The Nemesis can be configured to work with a variety of expression pedals and footswitches for various external control options.
Sustain your delay sounds with the HOLD function. The delayed audio will be repeated infinitely for ambient sustain effects.
Built-In Delay Types
Digital: A classic, clear digital delay with optional delay time modulation. The intensity knob controls filtering allowing for high pass filters (creating a thinner delay sound) or low pass filters (creating a warmer delay sound). 12 o’clock on the Intensity knob offers a 100% pure, unfiltered delay.
Diffuse: A delay line with a diffusion effect that smears the attack of the repeated signal, softening it and allowing it to blend in more easily with the unprocessed dry signal. This creates an ethereal sound reminiscent of classic “oil can” delay systems.
Analog: The sound of classic, bucket-brigade analog delays. Successive delays are warm, resonant and increasingly lo-fi.
Tape: A detailed re-creation of classic moving-head tape delays, Tape mode captures all the characteristic flutter, warmth, and color that give vintage tape delay machines like the Echoplex and Space Echo their classic charm.
Noise Tape: A detailed re-creation of classic fixed-head tape delays, Noise Tape is grittier and darker than the Tape engine, capturing the sound of old or damaged tape.
Degrade: A primitive lo-fi digital delay with bit crushing and sample rate reduction, Degrade creates esoteric retro sounds with varying amounts of distortion, noise, and aliasing.
Shifter: A delay with polyphonic pitch-shifting on the delayed signal, Shifter lets you choose octaves (either up or down), minor or major 3rds, 4ths, and 5ths.
Helix: This delay effect combines reverse delay with an octave-up pitch shift to create a shimmering delay that disappears into the upper frequency range.
Reverse: This classic reverse-tape effect recreates a sound made popular by many guitarists of the psychedelic era. The Nemesis creates several overlapping reversed delays that fade in and fade out regularly to create a pulsing tremolo effect.
Sweeper: A resonant low pass filter slowly sweeps across the frequency range, creating an undulating synth-like effect.
Rhythmic: The Nemesis delay line contains 5 delay taps. This allows for the creation of rhythmic patterns in the delay effect. The Rhythmic effect uses 3 taps to create a wide variety of 3-note rhythms (plus a note on the downbeat of the next measure). More complex rhythms involving 4 notes are available in the extended delay engines accessible via the Neuro App or MIDI.
Controls at a Glance
Mix Knob: This controls the relative level between the dry input signal and the wet, processed signal. When set at 12 o'clock, the wet and dry signals will be at equal volume. Fully counter-clockwise is 100% dry, and fully clockwise is 100% wet.
Feedback Knob: This controls the amount of wet signal that is fed back into the delay effect. At minimum feedback, the delay effect will only process once. At maximum feedback, the delays will continue infinitely. It is also possible to set a feedback greater than 1, allowing for "self-oscillation" effects.
Mod Knob: This controls the depth of the modulation applied to the effect. It can have different functions depending on which engine is selected. Some effect engines use time (pitch) modulation, filter modulation, tape modulation (wow and flutter), or tremolo.
Rate Knob: This controls the speed of the time (pitch) modulation, filter modulation, wow and flutter, or tremolo. In tape delays, this simulates the tape speed.
Intensity Knob: This knob changes function depending on which engine is selected. Most effect engines can create a range of different sounds: warm to bright, clean to distorted, full to thin, and so on. This knob changes the color or character of the sound, allowing you to dial in the flavor, so to speak, for each effect engine.
Engine Selector Knob: This control selects between the 12 main effect engines. To access the additional extended delay engines (the “back 12”), you’ll need to use the Neuro App or MIDI.
Preset Select/Save Button: This button selects and loads one of the four user presets saved in the Nemesis. To save a preset into the currently selected spot, press and hold this button.
Tap Tempo Footswitch: Tap this footswitch two or more times to set the primary delay time. Make sure the Subdivision Switch is set to quarter notes for basic quarter note operation. Press and hold the Tap footswitch to active Hold mode. This will circulate the audio in the delay line infinitely until the Tap switch is released.
Tap Tempo Subdivision Switch: Selects a beat subdivision for tap tempo, allowing more complex delay times such as dotted eighths and triplets to be tapped in using the Tap Tempo Footswitch. The Tap LED will always blink in time with the duration you tapped in with the Tap Tempo Footswitch, even if a subdivision is selected.
On/Off Footswitch: Engages or bypasses the delay effect.
Connections at a Glance
Input 2: In contrast to Input 1, this jack has quite a few possible uses; sure, you can route secondary audio input for stereo sources, but you can also use this jack as an external feedback loop input (i.e., a “return”), or as the data connection to your mobile device when using the Neuro App. In this way, the Neuro App sends data to the pedal using your mobile device’s headphone jack. Connect it to your mobile device using an included stereo 3.5mm to 1/4" cable. The input can also accept daisy-chained Neuro data from another Neuro-compatible pedal in the chain, if 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. This allows audio and Neuro data to flow on the same cable.
Output 1: This is the primary audio output. Connect it to your amplifier, recording interface, or the next device in your effects signal chain using a mono (TS) 1/4" cable.
Output 2: Much like Input 2, this jack can act as the secondary audio output, as an External Loop Send (if the pedal is configured in a routing mode that includes an external loop), or as a data connection for the Neuro App, passing data from the Nemesis 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) 1/4" cable. As described above, 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. This allows audio and Neuro data to flow on the same cable.
Control Input: This 3.5mm port connects to external control devices such as the Source Audio Dual Expression Pedal, Reflex Universal Expression Pedal, Neuro Hub, and Hot Hand Motion Controller. Using this port, you can access Source Audio’s proprietary Hot Hand technology, which allow you to control assignable parameters from a ring-like accelerometer that you’d wear around a finger on your picking hand.
Expression/Switch Pedal Input: Yes, you can hook up a compatible expression pedal via the 3.5mm input described above. However, this jack will allow you to plug in an external passive expression pedal or footswitch. A Pedal In Switch near the jack lets you select which type of external controller is being used. Set to Exp for expression control or Switch for footswitch control.
MIDI Input: This is a standard 5-pin DIN connector that accepts MIDI control messages from external devices, including program changes, continuous controllers (CCs), and MIDI clock
MIDI Thru: This is a standard 5-pin DIN connector that echoes MIDI messages from the MIDI Input jack and sends them to other devices. The Nemesis does not generate any of its own MIDI data, but it will copy and output any data it receives.
