heard the clips and lets call them "T" and "Cider" for comparison purposes. I've only used the TNT in passing so I don't have much experience dealing with them but my guess is "cider" is the tube channel and the "T" channel is the solid state channel. you can't go wrong with either choice, really, so it depends what you are pitting the guitars against in other parts of the mix.
i did notice some things about the recordings, namely, the difference in gain hiss. "T" had more detail you could have decreased the gain a bit on the pre to produce a more cleaner recording. "Cider" had a darker sound with less hiss but more pronounced mids that helped mellow out the recording - for classical finger picking, i'd prefer "T" because it pops out a lot more and you have more to work with if you want it as the center piece for your recording. for steel string work, i'd choose "cider" with phosphor bronze strings to cut the edge back a bit and give it a more organic feel. both recordings had lots of detail and you've got a great set of pre choices for your recording projects.
