thebass,
Even though there are a lot of tones I can get out of the SF-2 that I can not get out of the Series II bass controls, they tended to be sounds that I only used in my basement. As much as I liked the SF-2, it really came down to taking it out of my rack when I played out (weight thing)and putting it back in when I got home for just having fun in my music room.
If I broaden my music horizons to more edgy jazz / fusion stuff from the current gospel / retro-funk that I do now, I may cop another one.
Peace,
James
