Here's the specs (5 string bass) -Alder body with flame maple top (deluxe 5) -Pauo-ferro fretboard on maple neck (fretted) -tk-5 string through or top load bridge - two J style pickups Bassically I love my jazz bass's tone, and want this fiver to turn out with that tone, just the best possible version of it. The two settings I play with most on my jazz are bridge solo with tone rolled almost all the way off; and both full on tone 3/4 way up. Those are my fingerstlye and slap tones respectively. With my band I usually have the neck rolled off to about 75, with the tone rolled either a 1/4 back or a 1/2 back. *Edit- For the Bart P'ups, the 59J's seem like a nice option, but I can't edit the poll. Please vote on the poll and than if you can give your reason and favorite pre-amp.
