If you're looking for recording preamp for guitar, I have found that I wasted my time exploring much beyond a Lexicon Signature 284. Although it only prodices pretty much one sound, the sound is stunningly pheononminal! To get around this, you'll also need a really nice guitar FX rack box with a foot-controller (which is another $1000-$2000), but it's alright because while you're saving up for that, you'll still be so stunned and in love with the tone and showing it off to you're friends. It runs about around $1000 and I know AMS is now selling it for $700. You can also by the 2x10 cabniet custom made by Mojo for Lexicon for around $500 which I recommend although the preamp does have a loaded simulator in it.
