Hi Stewart,
since I'm new to the forum and the topic, and since I'm no native speaker, I don't have any clue what "SPDIF" and "DAW" means... suppose it must be something technical though.
I *did* understand that you talk about reamping: No, I don't do that. The guitar signal is already a complete guitar signal when recorded. The only thing missing is "room". My (very personal) reason for that is: I don't like to make the band sound like playing in different rooms (I associate that with 80s in general and Duran Duran in particular). So I try to use as few rooms (i.e. reverbs/delays) as possible for the whole song, including the backline, brass, voc. guit. etc., and to only differ in the amount of room that I add to every instrument or group of instruments. To my ear, results are more natural than when using different rooms for every instrument, although everyone of them by *itself* might sound better with its own reverb. But that's just my personal approach - I'm no professional in that issue. That means for the guitar that it won't get a "spring rev." or something guitaristic, but only its own amount of what the rest of the band gets.
(Was that understandable?)
Whatever,
Michael
