text: the difference between guitar workstations? i am looking for a workstation with authentic tone of classic amps along with being able to create your very own unique sound.  if you know any that are very good please tell.    also, i am looking at a couple right now, being the boss gt-8 processor and the digitech gnx4 and gnx3000.  which out of three would work better and also can the gnx4 and gnx3000 save custom sounds for use later.  so whichever one is the best out of both and also if you have any suggestions please list.  thank you for looking. http://www.line6.com/podxtlive/  i like this one a lot.
