Plug in. Tune up. Play a chord. If it needs more bite, turn it up. If the low strings need to hit harder, add Pulp. If the top end is getting in the way, move the microphone. Ample Juice works like the rig you already understand, because playing guitar should not feel like programming one. ONE SCREEN, LIKE AN AMP The whole signal path is in front of you: gate, boost, drive, amp, 4x12 and microphone. No pages to remember and no puzzle of hidden settings. Start with the controls you know, turn them until the guitar sits right, and leave the rest alone. FROM CLEAN ENOUGH TO LEAD READY Juice covers the ground between edge-of-breakup rhythm and a full lead voice. The first part of the dial adds body and sheen. The middle is where crunch lives. The last stretch opens quickly for sustain and saturation. Even when the gain is up, chords keep their notes instead of folding into one fizzy block. Pulp sits before the amp, where your boost pedal would. It trims low end before the clipping starts and leans into the midrange, so palm mutes land firmly and down-tuned riffs do not spread across the floor. Throw the Clean lever and the drive section steps aside; throw it back and every dirty setting is waiting where you left it. POSITION THE MIC BY TOUCH OR MOUSE No need to translate what you hear into studio jargon. Put a finger on the mic and move it, or grab it with a mouse. Position it toward the cone centre for cut, toward the edge for warmth, farther back for space, or off-axis to soften a sharp pick attack. The cabinet picture is the control—move what you see and listen as the tone follows. READY WHEN THE RIFF ARRIVES Use it as an AUv3 effect in your host or open the standalone app and choose your interface input. It adds no latency, so the note stays under your fingers. The tuner is already at the front of the rig, presets can save without stopping playback, and every control can follow MIDI or automation. 25 factory presets give you useful starting points for clean, crunch, metal, lead and more. Save the sounds that belong to your songs and take them across your devices.

Features
Read full description

Seyfert is a delay unlike your others: every echo spawns at its own place in an orbit around you, and the whole constellation slowly revolves. Turn up Feedback and you don't just add repeats, you spawn more echoes into the orbit, from a single tight slap to a dense, spiralling cloud. Spin revolves the whole field around you. Doppler bends the echoes in pitch as they whirl toward and away. 3D wraps them around your head on headphones. Lift the repeats an octave into crystalline shimmer, drop them a sub-octave for weight, or detune them into a chorus. A lush reverb blooms around the echoes, never the dry signal, so your source stays clear while the repeats dissolve into space. Features: - Orbital echoes, where Feedback sets how many circle you - Spin, from a gentle drift to a full whirl - Doppler pitch-bend as the orbit turns - 3D binaural imaging for headphones - Shimmer and transpose, up or down one octave (octaves, fifths, sub-octaves) - Per-echo Trail tone, tape Wobble, and Drive - Lush reverb applied to the echoes - Full 5-band EQ on the wet signal - Orbit and Ping-Pong patterns, tempo sync - 18 factory presets, plus save your own - Standalone app and Audio Unit (AUv3) for GarageBand, AUM, Logic, and more No accounts, no tracking, no data collected. Everything stays on your device.
