JamUp

JamUp is a top-tier mobile multi‑effects processor for guitar and bass. It delivers real-time amp and effects modeling, drag‑and‑drop tone design, and seamless integration with Positive Grid’s BIAS Amp to create a unified professional guitar system. With ToneCloud, you can access and share over 10,000 presets from artists, users, and the Positive Grid team, and optional expansions unlock up to 52 amp channels and 50 effects. Features include a complete 8‑track recorder (via in‑app purchase), 128‑slot preset manager, live view, tuner, metronome, MIDI learning, and more.

JamUp also supports importing songs from iTunes, time‑stretching tempo and pitch, and recording/ layering ideas with the Jam Player and sound‑on‑sound phrase sampler. Tone sharing lets you download or publish presets, while Audiobus support and a robust signal‑path editor make it ideal for live performance, jamming, and mobile recording on iOS devices.
