So there's a new Pod HD500. There are 2 useful features that should have been incorporated: a channel-switching jack, and spillover delay when changing patches.
The spillover topic has been discussed over & over, but Line 6 wants us to use the dual chains and pan/switch back & forth within the same patch. Sometimes you want to go from a lead to a totally different sound, like back to a clean patch instead of rhythm distortion. Being able to choose your next patch and know the delay will trail off after you switch back to rhythm is really really cool. I have had Rocktron and Digitech units that do this, and it is really musical, and easy to do (set "spillover on" and you are done).To be fair, the floor units from these companies do not have spillover, but Boss units can be "tricked" into spillover by matching delay settings on the destination patch and turning the delay off.
If this feature requires more circuitboard real estate, I would welcome a Longboard-sized Pod HD Super-Duper-Stage-Pro version, with more patches per bank, a second C/C pedal and the ability to have spillover.
I just watched a video describing the 4-cable method, to get your amp preamp tone in the loop of the Pod HD500. However, the Pod does not have an external control jack, to trigger channel changing on your amp. Perhaps with a Longboard-size Pro Pod, it could be added.
These two features would make any future versions of Pod much more useful and desirrable. Even if the price point had to squeak up a notch to accomodate it, guitarists would likely go for it to get those features.
Maybe the Pod HD500 MKIII??? Any thoughts?
