GarageBand on the iPad is pretty great, but it's kind of hard—and really unwieldy—to cram all of the necessary controls onto an iPad screen. Griffin's new StompBox foot controller for iOS makes things easier.
The StompBox provides virtual guitar effects using a pedalboard, so you can use your iOS device as a programmable effects board for your guitar. It comes with a GuitarConnect cable, which can simultaneously connect to instruments, headphones and an iOS device. The pedalboard also works with Griffin's teleprompter iPad app Qscript, to let you scroll through slides.
All of this sounds great and all, but I kind of feel like strapping an iPad to your guitar takes away some of the cool factor. [Griffin]
