Source Audio SA 251 / Ultrawave Multiband Bass Processor

The Source Audio Ultrawave Multiband Bass Processor explores the ground-shaking potential of advance overdrive and tremolo effects with the bass. At the Ultrawave’s core is a dynamic and multidimensional approach known as multiband processing. This process splits the frequency spectrum of the signal into multiple, discrete frequency bands especially tuned to the bass, and equips each band with its own array of adjustable parameters. In the case of overdrive, the Ultrawave splits the incoming signal and provides separate drive and output level controls for each individual band. The result is a thick and punchy 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 (a method of distortion often heard in the world of synthesizers), Octave Up, Negative Flip Diode, and more. The Ultrawave Bass also has an incredible companion collection of innovative sound processing blocks that take bass tone into endless miles of unexplored territory. These are found in the Neuro Desktop Editor (free editing software for Mac or Windows) or Neuro Mobile App (free for iOS and 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 Morph feature explores the marvelous potential of sound morphing, which allows bassists to smoothly transition from one thunderous tone to another with an external expression pedal, LFO, or envelope follower. The Ultrawave 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.
