Yeah, the CTP does sound pretty good and it's definitely an homage to what Alembic has done with the Fender design. I go back and forth. It's a little frustrating as my reaction is Wow, this sounds great! and then No, wait, this sounds great! An embarrassment of riches these days! I don't think you're losing anything by sticking with the F2B except perhaps the reverb.
My F2B needs a bit of love, probably just microphonic tubes, so it's hanging out in the home studio right now. My next task is to get it all back up to snuff and then pair it with the Grace Design Felix, used as DI box, and the Peavey (I still cringe when I type that, but it does sound damn good) IPR 3000.
