I am going to check out the GK neo with a precision bass. That "honky" sound is close to what I am looking for. The F cab sounds like a studio monitor to me. It sounds like something I would run the whole band through, not my bass. If clear and clean and loud is what you are looking for without any color then the F cab has it in spades.
I like the "personality" of the Neo cab...
I tried an F215 about a year or so ago. While it can be like a studio monitor, it would give out whatever you put in. I was trying it with my GK 800RB and it sounded wonderful. Of course, I turned the highs off for that old school type of tone. It gave it in spades. That's why Don Barry said that I might be happier with the Dually but I can say that the F215 was probably the best cab I've ever played through. So, if your amp produces a clinical clean tone, then the F cabs will reproduce that. If your amp produces a warm tubey tone, then that's what comes out. These are definitely high end cabs.
