It is a three-way blend of your input signal, a monophonic analog-style synth and footswitch-enabled octaves, all crushed by a distortion stage with a resonant lowpass filter that can sit before or after the dirt. If you want overdrive and Uni-Vibe rather than fuzz and synth, that is \u003ca href=\"\/products\/eventide-riptide-drive-uni-vibe\"\u003eRiptide\u003c\/a\u003e.

Eventide includes a universal power supply with US, EU, UK, JP and AU adapters. Power comes from the DC jack only; Eventide does not publish battery operation for this pedal. Bypass is selectable between Buffered, Relay, DSP+FX and Kill dry, so you can run relay (true) bypass at the front of a board or keep the buffer and effect tails alive inside an amp loop. A rear Guitar\/Line level switch matches the pedal to a guitar, a synth, an effects loop or an audio interface, and a Mono\/Stereo switch sets how the TRS input is read.\u003c\/p\u003e\u003ch3\u003eTechnical specifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eType\u003c\/th\u003e\n\u003ctd\u003eSub-octave fuzz with analog-style synth voice\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDimensions\u003c\/th\u003e\n\u003ctd\u003e10.8 x 10.2 x 4.3 cm (L x W x H)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAlgorithms and presets\u003c\/th\u003e\n\u003ctd\u003eSub-octave fuzz with monophonic synth and resonant filter; five presets, onboard switching needs an aux switch, more over MIDI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAudio I\/O\u003c\/th\u003e\n\u003ctd\u003eInput: 1\/4\" TRS (mono on tip, stereo on tip and ring).

The octaves are footswitch enabled, so upper and sub octaves come in and out without reaching down to the pedal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does moving the filter before or after the distortion change?\u003c\/strong\u003e Filtering before the distortion shapes what gets crushed, giving a smoother, more synth-like result. Filtering after it sweeps the finished fuzz, which is rawer and more vocal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I change presets from the pedal itself?\u003c\/strong\u003e Knife Drop holds five presets, but onboard preset switching requires an additional auxiliary switch on the EXP jack.
