POD HD features 22 brand new Line 6 HD amp models including: Fender® Twin Reverb®, HiWatt® Custom 100, Supro® S6616, Gibson® EH-185, Divided by 13 JRT 9/15, Dr. Z® Route 66, Vox® AC-30 (Top Boost), Marshall® JTM-45 MkII, Park 75, Mesa/Boogie® Dual Rectifier®, ENGL® Fireball 100 and more.

I liked the Signal Flow View where an entire signal chain (made up of eleven slots) is shown with the ability to change the specific effect in each slot and its position within the chain. The effects modeled are: dynamics, distortion, modulation, filter, pitch, EQ, delay, reverb, volume/panning, and wah. These effects can be inserted in front or after of your choice of 33 different amp and pre-amp models. The new firmware ver 1.3 update adds six more--three fenders, two British models, and a Line 6 hybrid plus five more amp parameters. Each of the effects is malleable with some modifications difficult to do in the real world of hardware such as changing the coil in the wah from the Italian Fassel type to another.

Not only are the amps selectable, you can set up dual amps and also the speaker cab and the kind of mic and whether it is on or off axis etc. This depth of adjustability is new for pedal--it was previously only available in computer-based plug-ins. I like that POD HD keeps the tradition of earlier PODs alive with a set of guitar amp knobs ready to grab at any time to dial in tone.
