Thank you for this. In most cases I would agree entirely (I still agree for the most part and I am not hung up on the visuals of where the gain knob ends up).
I play a passive bass with what I would consider a moderate output and typically dial the Gain down to 3.5 out of 10. Below ~3/10, it starts to lose detail and the signal-to-noise ratio starts to become unfavorable (being picky, here -- definitely usable but still noticeable). Much above 4/10 and the limiting starts to bug me a bit -- this is for my typical, pretty clean/uncompressed style of play; there are situations in which the action of the limiter is fun and musically advantageous (and, again, I recognize that a lot of people like it).
I don't think I've ever had the BB800 up to full output, but, even with the Gain at 3.5/10, I've never had to crank the Master to get as loud as I wanted to (loud enough to keep up with an active drummer in practice, running through a single, 8 Ohm cab). Maybe I'll have a better handle on this if and when I get to use it in a louder, live situation, but I haven't noticed a problem there, so far.
The rather obvious step of trying the pad hadn't occurred to me -- I am so habituated to not using (and not liking) them. I'll give it a shot the next time I plug into the amp. It'll be a cheap, easily reversible experiment (my favorite kind).
As it is, I'm not saying that the limiter is bad, just that, if they were designing the amp specifically for me, it would come on a little later and its action would be a little lighter. I notice a difference, there, when running into the front vs. the back of the amp (if one is running a pedal or some other sort of pre between the bass and it) but it's pretty easy to try that, too, and decide which way you like better.
