Do these effects units use the exact same code for the algorithms as the multi-fx units by line 6? e.g., is it better to get somethign like the POD HD for 500$ vs all the 4 button units(I think there is 5 of them) for about 1000$?
I'm only considering sound quality there as I like 4 button units. I have a GT-10 and I'm not at all impressed with the sound but I do like the convenience.
