What do they mean by designed for in front of amp? Other than line vs instrument level, it's bs.
If you run a delay in the front of a high gain amp, I don't care what the manufacturer tells you, the delays are going to smear all over the place because you're distorting the signal AND the delays.
Sorry Pete, but I'll disagree a little bit - there are a couple of other factors that come into play. (This has nothing to do with the Line6. I owned one but don't really know much about it and never an it into a dirty amp...but just talking in general.)
For example, if the delay is a ducking delay, you'll have less problem running into a dirty amp because they delay won't be piling on top of your 'live' playing as much. Something like an echoplex doesn't have a ducking feature per se, but the way it reacts to the input results in kind of a natural ducking. Also, IMO, a delay that puts out a narrower frequency range will smear less...for the same reason...less frequency overlap with your 'live' playing. So a tape, analog, or analog-sim type of delay with a narrower freq response will work better than a full-range digital delay. Again, IMO.
And last but not least, how your amp is set and how it reacts to the input will affect things too. If it's real sensitive to input, then as the delay trails off, it will clean up a LOT as if you were rolling the guitar volume way down.
Yeah, it will never be as 'clean' as running the echo in the loop or post-amp, but it isn't a totally lost cause. It all adds up and IMO, every guitar->delay->amp combination will be different. And that doesn't even take settings into consideration, really.
