I picked up Recabinet 3 awhile back for recording Guitar, and it made a huge difference going from the POD HD's internal Cab/Mic simulation to Recabinet's.
Anyway, I was happy with my Bass tone with the POD HD, but since Recabinet had Bass Cabs I figured I'd give them a try, and turns out I really liked them. Felt like they sit in mixes a bit better overall, and the ability to change and tweak them after I'm done recording is a huge bonus. http://youtu.be/hVVR9gJd7Uw
The first half of the video is comparing an identical Cab/Mic setup, and the second half is comparing my custom Recabinet Cab/Mic setup to the POD HD.
Figured this might be of some use to my fellow home studio guys
