Mobile POD is Line 6's guitar amp modeling software for iOS and is the companion of their Mobile In Hardware.

Note that you will need Line 6's Mobile In digital guitar interface to make this app work. Since Mobile In uses the digital input of your iOS device, it provides better signal quality, however it makes the app incompatible with other interfaces that use the audio output jack.

The Mobile POD app puts the popular amp tones that Line 6 has been emulating within your iPhone and iPad. You get up to 64 models of effects, speakers and guitar amps, with each virtual gear being fully tweakable and bearing the same Line 6 quality as their other products.

Features:

• 32 Guitar Amps
• 16 Speaker Cabinets
• 16 Stompbox and Rack effects
• 10,000 Preset tones
• Built in Tuner
