Just ordered a POD HD 300 from Sweetwater. Thanks to my lovely lady. :)
I guess they've been discontinued or replaced, I don't know. Seems I grabbed the last one - a demo at that.
The 400 and 500 didn't do anything I couldn't live with. The rack version is too expensive for my purpose. I have a love/hate relationship w/ the classic bean. For over $100 less, and with the expression pedal and footswitching, the HD 300 looked like my best bet. I'm guessing that I'll do most deep tweaking via the computer, anyway.
I've been recording more and more guitar tracks recently and I came to the conclusion that my best bet was to mix and match. Throw a mic in front of a low wattage small amp and beef it up with an overdub using a POD or the Spider. One thing I know is that I really prefer not to rely on software. Personal preference.
Anyway, I sort of came to the conclusion that I probably won't ever be able to get the sound I want w/o cheating a bit. There's no way I can record a big Marshall amp or Mesa Boogie w/ a full size cab around here. I simply cannot generate the kind of volume I need to record something that really sounds like what it should sound like: loud guitars.
That being said, I'm still planning and budgeting the tube amp - most likely the Marshall DSL or a Blackstar HT-5R.
