I actually didn't notice much of a difference when going out of the guitar, into a DI, into the 002.

If your recording guitar.. I would either:
a. mic the amplifier
b. go pre-out of the amplifier into the 002
c. line 6 pod into the 002

but not...
d. direct out of your guitar into the 002
e. direct out of your guitar into DI into 002

"A" will get you the sound of your amplifier colored by the sound of your mic
"B" gets you the sound of your amplifier
"C" gets you the sound of whatever amplifier model you select from the pod
"D" gets you this thin, lame signal
"E" gets you this thin, lame signal with a brick.

At least thats what it seems like whenever I've recorded guitars which is admittedly not alot.
