hey lestat,
i haven't used cakewalk's
audio FX 2, but it looks pretty neat. there is a demo available from cakewalk, which i might try out later...you can also get a demo of ReValver thru the cakewalk site.
does your amp have an effects loop on it? if it does, you can go out of the effects send on your amp and into your sound card...this would allow you to use the preamp on your crate....if you are going to record direct it is better to have some kind of preamp than to go directly from your guitar to the soundcard. a good sounding guitar preamp can help you get the sound you're going for...
i haven't heard the crate amp...do you like the sound coming thru the cabinet? if so , micing the amp is an idea, like i said before...but if you were gonna try this it would be nice to have a mixer so that you could get a good signal going into the soundcard.....to be honest, i've never tried to record guitars using a mic that plugs into the mini jack on a sound card..so i don't know what you can hope to get this way....
you said that you got all the plug ins loaded...do you mean installed? i thought you were getting an out of memory message when you tried to load some plug ins.....have you been able to use plug ins with the vst wrapper? if you can't use any plug ins without the 'out of memory' message, then it is likely that guitar tracks didn't install properly, or that a file got corrupted...
as far as soundcards go, right now i'm using a delta 66 with a breakout box (the breakout box is called 'omni i/o) which has two preamps on it...i've been plugging my guitar directly into omni and playing thru
the ReValver plug in in SONAR...i've also used a POD from line 6 and SANS AMP CLASSIC for recording direct stuff...some of the ZOOM pedals are also designed for direct recording.....there are a lot of options today for recording and processing guitar , so i'm sure you'll find something you like...though, for now, the first thing i'd try is going out of the effects loop on your amp, if it has one....then use some plug ins on your tracks to get a fuller sound...the cakewalk fxs or revalver might be good for getting a more vintage sound (used in conjunction with the preamp on your crate).(btw, in ReValver you can bypass the 'preamp' in the plug in if you are using your amp, and just use the effects and power amps in the plug in....i don't know if the cakewalk fxs will do this)...if all you're recording is guitar, you might also try recording the same track two or three times and pan them differently, this can really beef up the sound....
