Have you already heard about the new POD HD line? (POD HD300, 400 and 500).
They claim it has 10 times more capacity on amp modeling (by the way there are only 16 amp models). The reviews I've seen so far are enthusiastic. I'm pretty interested. I gess the POD site can say much more than me. http://line6.com/podhd/ Sorry, Now I found similar topics. This post has been edited by Keep_Rocking: Dec 2 2010, 05:08 PM |

I've heard some good things about it!
I'll perfer a few great amp models rather than hundreds of crappy ones. I'm sure however they will try sell more model packs separately for it, like they did previous versions... My POD XT sounded quite digital and not high gain, until you purchase those extra model packs (metal pack made a big difference). The thing is it's all there already, there's just an expensive purchase for a simple key to unlock it. After the unlocks however, I'm quite happy with the tones (tweaked). Like to know how the POD HD compares to them? --------------------  Play Games Arcade Take a break, Play Games!

Thank you guys for your opinions.
It's very nice to know what you think, as you already have previous PODs. |

The new Pod HD is doing something that no other pedals have done until now. It's using "Hypersampling" to essentially use sounds that are too high or too low for the human ear to hear, but which can effect the sounds we can hear. These are called Subharmonics and Superharmonics. This way, they get closer to a real amp sound as it's close to an analogue sounds. You couldn't really do this until recently with a pedal board as the processing requirements were to great and you'd have to attach a big computer to your pedal. Now it can be done. Yay for technology

Todd Cynic that I am the bit about subharmonics sounds particularly like marketing spin to me Todd . Instruments do produce subharmonics and they can and do have a psychoacoustic affect. A church organ for instance can produce really low sub-bass fundamental frequencies and subharmonics below out audible range that physically set the diaphragm/chest to resonate. Our audible range runs 20-20KHz, so L6 are claiming it produces subharmonics below 20Hz (and superharmonics over 20kHz). For a guitar anything below @100Hz will have to be a subharmonic and these will attenuate very rapidly so to get below 20Hz you would be talking about the third, forth or higher subharmonic. I think that at third or higher subharmonic you'd need an amp/speaker capable of producing well over 150dBA (SPL) at 1 meter to get any psychoacoustic affect simply because the subharmonic would need a system with a massive dynamic range as the level would be so low. I don't think that there are any power amps capable of that and if there are then any other signal present in the audible range would generate such a high volume and SPL that you would go deaf and so on. For superharmonics it's possible. For guitar signal above @5kHz a are mainly harmonics anyway. Up at 20kHz and over you are again talking about very high order harmonics (or superharmonics). To produce these accurately though on a digital system you'd need to have a sample rate at 100kHz or higher to avoid ringing and aliasing affects and on modern equipment that means using a sample rate of 192kHz or 384kHz. Modern pro audio can and do have this facility but a lot of home studio audio is fixed at 96kHz and below (some are fixed at 44.1). Again once you are beyond 3rd order harmonics, and so in to superharmonics, you would need an extremely low noise floor to hear them. So again you would need a power amp that is able to reproduce a huge dynamic range etc. So whilst the PodHD may be able to do it but you will run in to issues trying to reproduce it. But maybe I'm just a cynic
