I recently received this Waves iGTR to review and luckily it has an output for recording so I was able to record a video showing the sounds that are capable from this iPod style headphone amplifier. Aside from 3 amp types it also has built in effects, Reverb, Delay, Chorus, Wah, Tremelo, Phaser. It also has an aux input to plug in an mp3 player which has a separate volume knob to balance the levels. It has 2 outputs one for headphones and one for recording and you can also chain iGTR’s together so that you can jam with friends! Fantastic idea. Check out the video, I tried to cover all bases.
