Put simply: a multi-band processor. In detail, this means that frequency bands are split up here and can be tackled separately. That doesn't sound exciting at first, but the Source Audio Ultrawave has 37 splitting options. You can arrange the bands in different ways and separate pairs of 2 to 10. The result is a huge number of potential sounds with their own character. The signal chain with a classic touch allows compressors and expanders to be packed before or after the distorted signal and modulated afterwards. Here you have the option of using an LFO to control what works and, in addition to flanger and phaser-like sounds, you can also create tremolo sounds, for example. The frequency bands are correspondingly flexible. In addition, you can use the morphing function to create completely wacky sounds. Two parameter constellations can be superimposed here and controlled via LFO or envelope. Typical Source Audio –thinking outside the box. 

A few words about the connections - stereo outputs make sense, but two instrument inputs don't make the whole thing unexciting - being able to manipulate guitar and synth at the same time from the same LFO. I don't think that's available in pedal format. But the routing options don't stop there, the individual source audio devices can be merged together. If you use one input to send commands from the Neuro app, you can let them travel through the entire Source Audio signal chain. As already mentioned: EXP connection, MIDI and USB are included here. Well - if you know the C4 or the Nemesis, you know about the Neuro Editor. In my opinion, the coolest and clearest editor of this kind ever.
Incidentally, calibrating Source Audio with an app or editor is surprisingly easy and a lot of fun. One of the few in-house editors that justifies having a laptop next to the pedalboard. This is perhaps also the biggest problem of the Source Audio brand: despite all efforts to keep it simple, the applications are heavily dependent on the neuro app or the editor. And many musicians still like to avoid both.

Soundblox 2 - Dimension Reverb

Von außen betrachtet ist das Vertigo Tremolo aus der One Series ein recht geradliniges Pedal. Mit vier Reglern und drei, per Kippschalter anwählbaren Modi, bietet es bereits einiges an Kontrolle über den Sound des Tremolo Effekts. Und hier hat man bei weitem keine digitale Annäherung an Tremolo. Das Vertigo Tremolo klingt absolut wie ein echtes, tiefes und warmes Amp-Trem.
Verbindet man es via der gratis herunterladbaren Source Audio Neuro App mit dem Smartphone, eröffnet sich noch eine ganz neue Welt an Features wie progressiven Tremolo Patterns, zusätzlichen Modulationseffekten, parametrischen EQ Settings und vielem mehr. All diese Einstellungen können natürlich in den drei Kippschalter Positionen oder 128 MIDI Presets gespeichert und wieder abgerufen werden.

From the outside, the One Series Vertigo Tremolo is a very straight forward effects pedal. Four knobs, three presets accessible via toggle switch already give a lot of control over the sound of this tremolo device. And one doesn’t just get a digital approximation of a tremolo – the Vertigo Tremolo sounds absolutely like a real, deep, warm amp-trem.
Connected to a smart phone via the free Neuro App a new world of features like progressive tremolo patterns, additional modulation effects, parametric EQ settings and a lot more opens up to the user. All the settings of course can be saved to one of the three toggle positions or one of the 128 MIDI presets.

Vertigo Tremolo

The Source Audio Dual Expression Pedal delivers precision response and smooth action in a durable cast aluminum housing. Dual TRS expression outputs make it possible to control two effects units simultaneously. The pedal is compatible with the very common Boss/Roland style (“tip hot”) expression input. The Range Adjust Knob sets the bottom point of the expression range. Plus, a special Sensor Output connects directly to any Hot Hand®, Soundblox®, Soundblox 2, or Soundblox Pro pedal for real-time control over filter sweeps, effect modulation, LFO speeds, wet/dry mixes, drive levels and more.

Source Audio Dual Expression Pedal Controlling Multiple Effects

SA 161 Dual Expression Pedal

The Spectrum Intelligent Filter is the most powerful stereo filter effect pedal ever created. Building on almost 15 years of filter pedal technology and know-how, Spectrum is the culmination of Source Audio's finest envelope sounds and best thinking on how to easily incorporate those sounds into rigs of all types. The pedal not only features finely crafted envelope filter effects inspired by some of the most iconic and sought-after effects pedals on the market, it also includes buzzing, synth-like octave/distortion/filter effects. The pedal is a cleverly integrated, all-in-one funk/psych/electronic/jam machine. Whether you want to easily plug and play with its six carefully crafted factory sounds, browse the ever-growing Neuro library for additional sounds created by Source Audio and other Spectrum owners, or use the Neuro’s deep sound editing tools to create your own highly personalized presets, this filter pedal will satisfy the needs of any guitar, bass, keyboard, horn, or (insert your instrument here) player.
