Sonoma produces some fine music making apps, from the excellent StudioTrack multitrack recorder to the new GuitarTone amp simulator.

The perfect accessory comes in the form of the new GuitarJack Model 2. This simple adapter adds a 1/4-inch instrument input, a 1/8-inch mic input and a high-quality 1/8-inch headphone output to your iOS device.

The control panel, accessed through any Sonoma app, allows you to tweak input gain and impedance settings. All parameters are stored even if you quit the Sonoma software, allowing the device to be used with third-party apps.

It’s not the cheapest audio interface, but the adjustable impedance and gain options give the GuitarJack an edge over cheaper options.
