StompBox Band is a new iPad app that turns your tablet into not one but two guitar effect racks. It comes from 4Pocketsaudio, and is a beefed-up version of the original StompBox app.
Designed for bands or soloists who want a dual-effect rack, StompBox Band's racks can be run at the same time and their outputs sent to different channels (providing you have a suitable audio interface, that is). This means that it can be used by two guitarists simultaneously.
Other features include a Chord Explorer, which enables you to audition patches while tweaking them, and a Song Mode that you can use to save commonly-used patches and effects to song files.
There's support for AudioBus and Inter-App Audio, and owners of StompBox and StompBox Free can use their in-app purchases in StompBox Band.
You can find out more on the dedicated StompBox Band website, while the app can be purchased now from the Apple App Store (opens in new tab) priced at £17.99/$25.99.
