Not at this time. My primary reasons for picking the Studio 40 over the regular one were: a) the FX loop, b) the tweeter, c) the acoustic padding, d) the speaker, and e) the pre- and post-effects DI output option.Question for you: Do you use the modeling? The other features of the Studio 40 are certainly nice, but I’m not sure I’d use the modeling once I dialed in a “Rumble” sound.
That doesn't mean I'll never use more of the models (like the Ampeg B-15 and Fender Bassman, for example) in the future, but I have no regrets about spending the extra on the Studio 40.
Oh, and f) the black grill cloth!
