Phase 3 of Summer Strummer 2 is here, and it brings with it a 40% discount on the Multitrack upgrade for AmpliTube, which expands the recorder to 4-tracks on the iPhone/iPod touch, and 8-tracks on the iPad version. With the Multitrack installed, the app is ready for the AmpliTube Studio upgrade, which adds DAW-style editing. We’ve also discounted Loop Drummer style packs by 40% (single packs or the bundle), so you can stock up on the loops for your AmpliTube productions. These prices are only good through July 17, so act now!
