magicninja - that is some extremely fine info you've given me - that's the kind of thing i was trying to find out - which effects weould be better to keep in a box and which through a pc...
there is another option. has anyone tried the new g-system by tcelectronics? rack effects in a stompbox... that could be pretty incredible... i guess better than pod xtlive and digitech gx-4? line6 wise, i have the dl4 which is fantastic sounding and the ml4, not so great... so i don't know about the xtlive pro... i hear the digitech one lets you use 3rd party sofware effects like waves anyway so maybe that's a better option sound quality wise...
if anyone has any experience of these 3, it would be good to hear from ya!
cheers
