With over 80 effects and 16 hyper-realistic amp models, the Line 6 POD HD300 took 15 years of experience with amp modeling and 3 years of new research to create. Ten times more amp info was used to create these emulations, particularly of tube amplifiers like those with single-ended class A tube stages. From the Fender Twin Reverb to the Vox AC-30, the POD HD300 can mimic some of your favorite amps and then modify them with effects, looping, and more.
