Features
Read full description

Ember is a full drive chain in one pedal — not another single-circuit distortion. A gritty, tweed-flavored overdrive sits on the bottom, a filthy fuzz runs layered on top, and compression is built in. It's the stacked-amps sound that normally takes three pedals and an afternoon of gain-staging, dialed in with one knob. THREE VOICES WARM — distortion the way it was first discovered: a pushed vintage amp with sliced speaker cones. Raw, retro, and touch-sensitive. Roll BITE up and it tips into blown-speaker sizzle with a starved-supply quiver in the note. DRIVE — everything, more. A doubled, dual-amp crunch straight out of the 1980s. The sustain sings, sizzles, crackles, and rings — and stays articulate. Chords keep their edges; every note in a run stays clear. RAVAGE — unhinged. The amps are on fire and the ship is going down. Stomp BOOST and single notes bloom into screaming, feedback-laced sustain that hangs on for the better part of a minute. Pinch harmonics, smoldering solos, sixties-fuzz recklessness at modern gain. WHAT IT'S FOR • Recording guitar direct — a finished, layered drive tone with no amp, no mics, no reamping. • Replacing a drive + fuzz + compressor stack, and the hour spent making them agree. • Leads that hold: BOOST adds gain, presence, and a sustain compressor that carries the note for you. • Practice anywhere — standalone app, plug in and play. CONTROLS THAT MATTER • DRIVE — one knob from edge-of-breakup to inferno. The molten orb burns hotter as you push it — and as you play harder. • TONE — dark and thick to bright and cutting, with a speaker-style rolloff that keeps fizz out. • BITE — round and smooth to sharp and shredded. • BIAS — starve it for choked, dying-battery textures. • IN / OUT / MIX for gain staging and parallel blends, stereo or mono, click-free bypass. ON STAGE AND IN THE STUDIO • AUv3 for GarageBand, Logic Pro, AUM, and any Audio Unit host. • MIDI learn on everything — knobs, voices, BOOST, bypass, even program-change recall of specific presets. A MIDI footswitch runs the whole pedal hands-free. • Factory presets plus custom presets. One purchase. Mac, iPad, and iPhone.

About

RAUSI

Read full description

RAUSI is a dual-circuit high-gain distortion processor for iPhone and iPad. Use it as a standalone audio app or insert the included AUv3 effect in a compatible host such as GarageBand. FLOE and CRAG provide two contrasting distortion personalities inside one front panel. FLOE leans toward dense, abrasive wall-like saturation, while CRAG provides a tighter voice with deeper active EQ control for focused riffs and deliberate placement. FEATURES - FLOE and CRAG distortion modes - Adjustable Input, Drive, and Output - Active Low, Mid, High, and Mid Frequency controls - Selectable 9V / 18V headroom and saturation behavior - Instrument and line input modes - 2x and 4x oversampling modes - Standalone iOS/iPadOS app - AUv3 audio effect for compatible hosts TRY BEFORE UNLOCKING The working release model assumes 10 minutes of full-featured active use, shared between the standalone app and AUv3 extension. A one-time, non-consumable In-App Purchase unlocks unlimited use in both formats, with Restore Purchases available in the standalone app. Confirm this behavior in the production build before submission. RAUSI is designed for guitars, bass, synthesizers, drums, and parallel processing that need strong attack, dense harmonic weight, and controllable high-gain tone shaping.
