Now you can jam out wherever and whenever you want with the GuitarConnect Pro by Griffin ($80), which basically turns your iPad or iPhone into a mini performance platform. One end of the GuitarConnect Pro offers a 1/4″ mono instrument jack that fits your instrument cable while the other end gives users a dock connector for their iOS device. Once you plug your guitar or other instrument into the jack, you’ll experience a 100% noise-free, digital connection to GarageBand or any other Core Audio app. Better yet, the gain control knob on the side lets you regulate your input signal strength. Now, if only you had this much control over the rest of the band.
