Well I think a lot of the dry tracks signals are totally dependent on the type guitar used/pickups more so the DI box and interface. Don't get me wrong, of course a good DI box and interface helps. I've seen a lot of good re-amps coming from some bs interfaces too. All in all, I think if the guys good at reamping you'll get a killer sound regardless, but the source signal is dependent upon several things, like pickups, guitar, the player, picking, etc....You may just have to run a trial and error and see what works the best. Or do an A/B with your source dry tracks with what you have available. If that doesn't work then you'll know you need to change it up. Hope that helps.
