Sparse Neural FX Modeler

Amplifier captures & pedals

Free · Designed for iPad. Not verified for macOS.

Neural captures of real tube amps, a 20-block pedalboard, and studio effects — running live on your phone. Built on published research. Plug in and play through real amplifiers, captured with neural networks and reproduced live on your iPhone. Amber Neural FX Modeler models the sound of tube amps sample by sample. Pick from 25 captures — chiming Vox, clean Fender, cranked Deluxe Reverb, vintage fuzz — and play them in real time with latency low enough to feel like the amp is in the room. THE PEDALBOARD Twenty blocks you arrange in any order: up to four neural amps in one chain, drive, tape echo with wow and flutter, shimmer reverb, compressor, gate, wah, phaser, flanger, chorus, tremolo, EQ, octave, delay, and a convolution reverb. Drag blocks to reorder the signal path. Save and load your rigs as presets. RECORD YOUR TAKES One tap records both a dry and a processed track straight into the Files app. BUILT ON RESEARCH The engine comes from a published paper on efficient real-time neural amp modeling — the same models, running entirely on your device. No ads. No accounts. No data collected. Plug in a guitar through any audio interface, or just use the mic. Capture names identify the amplifiers the models were measured from; no affiliation or endorsement is implied.
