I don't have any experience on the DB750, but it is my uneducated guess that it would work fine in the studio, given any particular path to tape you take. If you like the sound, you're probably alright. One strange thing I like to do with amps I try to find out to what extent I can boost or cut mids, trebble, and lows. If the amp is capable of going to either extreme direction away from your prefered tone, it should be able to handle anything in between. Some amps with only a few knobs can do this (I don't yet like gaphic EQ's on bass amps very much). Though, I've had some amps, that even with some knobs set in crazy possitions, it's variation from the more neutral tone is pretty minimal; this means to me that it isn't the most versatile amp out there.
