The Line 6 POD HD Pro is a professional rackmount solution for all things amp modeling and digital effects. Perfect for studio experimentation or your live effects rack, the POD HD Pro offers high-definition models of 22 amps, 16 speakers, and over 100 effects for a range of tones that used to require a stocked warehouse full of gear. Go through the presets and find what you need, or tweak to your hearts content and save your favorite sounds for instant recall later. The onboard USB interface gives you direct-to-computer recording -- no need to mic an amp or go into a separate interface to put down your latest riff ideas or overdubs on your album.
