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.

Undae is an optical vibe, the watery and vocal swirl of the late sixties photocell units, rebuilt for iPhone, iPad and Mac. A single slow lamp sweeps a chain of staggered filters, so the notches roll through your tone unevenly instead of moving in a straight line. That stagger is what makes a vibe sound like a vibe and not a phaser. Chorus mode blends the sweep against your dry signal for the classic swirl. Vibrato mode drops the dry signal for a pure, seasick pitch wobble. Voice it to taste. Choose 2, 4, 6 or 8 stages, morph the lamp from a smooth sine to a lopsided ramp, move the sweep centre darker or brighter, and add a touch of feedback for a throatier, more vocal sweep. Set the speed by hand or lock the lamp to your project tempo. Spread it across the stereo field for a rotary style swirl, tilt the tone, then set mix and level. Twelve factory presets get you going, from Classic Chorus and Rotary Wide to Jet Phaser and Seasick, and you can save your own. Use it as an AUv3 audio effect in GarageBand, AUM, Loopy Pro, Cubasis, Logic and other hosts, with host presets, parameter automation and full session state. Or run it standalone with the built in demo bed, your microphone, or a song from your library, and export the processed result. Undae collects nothing. No accounts, no tracking, no analytics, no ads. All audio is processed on your device and is never recorded or uploaded.
