Im planning on Ultra-Jazz fives for my five string warmoth. I hear they give a nice classic jazz bass tone without the hum. If this a pretty accurate description? I also have read that the ultra series are notoriously low output. So what pre-amps are you guys using with them? Im thinking about which one I'd like to use, and the choices are Seymour Duncan basslines, EMG, Aguilar, bartolini. Im most likely planning on a 3-band, but would like to hear what you guys have, or what you think would work best to get pretty much a great jazz bass tone out of those pickups.
