I've got a Squier CV Jazz and a GK MB210. I'm playing with a 5-person combo that does primarily folk-rock type stuff, but we're doing a couple of songs where I'd love to come as close as possible to the sound of an upright (think smoky club at 2:00 AM for the kind of vibe I'm going for). I know I'll never really get that sound, but what's the best I can do with the equipment I've got? I'm not interested in buying a pedal or anything like that. What are the settings on the bass and amp and any playing techniques (where to pluck, whatever) that will get me as close as is possible?
