The B2.1u is pretty powerful. I use it all the time and like the flexibility it gives me to change the sound easily to match the music.
I know there have been some folks who have offered spreadsheets to record their unique settings. Here is my take on the same, most of the slots are blank with the first page filled in only to show how I would use it.
Hope it's helpful.
+1 on that.
It's very usable for recording and live performances. you can create some unique sounds with this multi-effects processor.
