Source Audio Overdrive and Tremolo Bass Guitar Effects Pedal with Multiband Processing, Onboard Compressor/Expander and 8-Band Graphic Equalizer

Source Audio Ultrawave Bass Multiband Processor explores the ground-shaking potential of advance overdrive and tremolo effects with electric bass. At Ultrawave's core is a dynamic and multi-dimensional approach known as multiband processing. This process splits the frequency spectrum of a guitar or synthesizer into multiple discrete frequency bands specially tuned for bass and equips each band with its own array of adjustable parameters.

  • 37 different band-splitting options: these options include single, 2, 3, 4, 8 and 10 bands with each band-splitting option having several sub-sets with different band-splitting frequency points
  • 44 different distortion types: choose from distortion/overdrive/fuzz types that include tube, diode, foldback, negative flip diode, octave up and more
  • Dual-channel compressor/expander: features include input gain, threshold, ratio, attack, release, frequency isolation, output gain controls with a detailed graphic monitor and the ability to place the compressor/expander before or after the overdrive module
  • Growing library of published presets: for quick and easy access to a world of great tones, try sampling sounds from a vast collection of published presets created by the Source Audio team and the ever-growing Ultrawave Neuro community
  • Stereo inputs and outputs: create two entirely different presets and run them in series, parallel or run each to a separate output or use the channel sync options and phase offset control to create stereo ping-pong tremolo effects
  • Detailed LFO controls: use the LFO module to control Ultrawave's tremolo, morphing or ring mod features with standard sine wave or attack/release controls to create highly customized LFO shapes
  • Sound morphing: change from one sound to another with an expression pedal, envelope follower or LFO
  • 8-band graphic equalizer
  • Adjustable noise gate
  • Assignable knobs: reassign all four of Ultrawave's knobs to the parameters most useful for making quick onstage changes and save a different set of knob assignments for every preset
  • External expression pedal control: make simultaneous, on-the-fly changes to up to three parameters with an external expression pedal
  • 6 toggle switch-accessible presets: quickly access up to 6 pedal presets with Ultrawave's toggle switch
  • MIDI capable: connect Ultrawave to the Source Audio Neuro Hub, access up to 128 presets with MIDI program change (PC) messages, control many of the pedal's parameters with MIDI continuous controller (CC) messages and sync LFO modulation speed to MIDI clock
  • USB port: the USB port provides access to deep editing possibilities and firmware updates Neuro Desktop Editor, and USB MIDI allows Ultrawave to work as a plug-and-play device with recording software running on macOS and Windows
  • Universal bypass: select either analog buffered or relay-based true bypass
  • Compact design: the durable, anodized aluminum housing has a small footprint and sturdy hardware

In the case of overdrive, Ultrawave Bass splits the incoming signal and provides separate drive and output level controls for each individual band. The result is a thick and rich distortion with loads of unique overtones and dynamic interplay. Split the signal into 1, 2, 3, 4, 8 or 10 frequency bands and apply any of the band-splitting options to an exciting collection of overdrive types, including tube, diode, foldback, octave up, negative flip diode and more.

​Ultrawave Bass also has an incredible companion collection of innovative sound processing blocks to take sound creation into vast new directions. These are found in the free Neuro desktop editor software for macOS/Windows) and Neuro mobile app for iOS/Android. All presets created in the Neuro editors can be loaded directly to the pedal, saved to a personal, cloud-based preset library and published to the Neuro community to be easily accessed by other Ultrawave owners.

The dual-channel compressor block includes studio-level controls that can be placed before or after the drive circuits. The multiband tremolo block provides individual control of each band's tremolo depth, rate and start time as well as its LFO wave shape. Changing the LFO wave shape and varying the tremolo start times of each frequency band creates fantastically propulsive sounds reminiscent of sequencer or arpeggiator effects.

The LFO's ring mod option creates waves of retro/futuristic industrialism. The morph feature explores the marvelous potential of sound morphing, which allows bassists to smoothly transition from one super-charged tone to another with an external expression pedal, LFO or envelope follower.

Ultrawave Bass also has advanced stereo features that can send entirely different drive effects to each of the outputs for a wide stereo field, place the effect in two places in a signal chain or generate mind-spinning, ping-pong tremolo effects. Plug in, turn up and explore the wonders of multiband processing built on over a decade of refinement and experimentation.
