My bad! Q knobs or frequency knobs, the chicken headed knobs are what they are. I never paid attention to the analytic aspect of the controls. Bob Novy was the master of that aspect, IMO. I sure hope he is doing alright these days. I miss his posts. I do get words and concepts backwards a lot these days. It is just the nature of the road I am on. Anyway - After a while of playing with the controls, you just get to know where they need to be to get the sound you want. This bass does not replace all your other basses, unless you needed to sell them to afford the beast. It never made me want to replace my other basses, Alembic of not-so Alembic ones. It was just a great playing, great sounding, great looking bass, that I could no longer play much any more, so it became a waste for me to be its custodian. On to a younger man to help him reach his potential, and just get a really good buzz from playing an excellent bass. This bass is all his now. I have no ownership rights to it at all anymore, and I am happy it stayed in the family. Who could ask for more?!
