hmm
I seem to have been down this road many times :lol:
Alright firstly the answer to your question:
If a multi effect IS what YOU want:
The BOSS gt-8 definitely gives better tones than the POD XT(live or no live),provided that you are willing to tweak it and also frequent the BOSS forums,some amazing guys there
The POD is a plug download and play interface,its good at what it does,but frankly its tones arent as good as the GT-8.
But in the end Shred is right,it might seem that a multi effect is gonna give you what you want,but in the end you will be dissatsified just a small 5% and you wont know where...and thats what you attribute true analgo sound to.
Get a Sansamp and nice Keyboard Amp,you seem like you have some money,so I am guessing you should have no problem building up yuopr rig in a few months.
cheers
ps,Currently playing through a gt-8,need a Sansamp :twisted:
