Do you want to know the response the instrument alone or with it connected to an amp and speakers? If the former, you could measure it completely within the electrical domain. Connect the instrument to the microphone input of a good sound card and grab a few samples of each string. If the latter, I'd take it outdoors and meaure it. You can do close microphone measurements too, but I think it's better to do bass measurements in an anechoic environment. Otherwise, indoors, you're really measuring the room more than the signal. It's hard to separate the influence of the room at bass frequencies.
