I just went through this debacle with my stuff.
I'd used reamping for other people and not had much trouble at all. Weak reamp signal (that turned out to be my X-Amp). But when it came to a bout of doing my own songs the reamps sounded shitty, overly distorted AND weak. I think the thread is still on 1st page if youre interested.
Summary; a few of the guys said that I was tracking them too hot. I was getting the absolute maximum peaks at about - 1 or -2 db. This was distorting the DIs on input. I found that the best level for my gear (ff800, J48 and now red eye) is absolute peak at about -8 - -10. I think one of the reasons I got away with it before is that I'm a very aggressive player, but the guys I've been recording arent, and I set the pre gain to my playing, so their tracks were cooler.
All things considered, after hearing the results of DIs tracked too hot, youre better off erring on the low gain on input side, and upping the gain on output and at the amp if you need to compensate. You can add more gain/distortion if you need it, you cant take it out if its in the DIs.
