I may be possibly picking up a used Brubaker Brute MJX-5 in the near future. Now the cool thing with this one is that the seller has upgraded the pickups to Nordtrands (NJ5 for the jazz pickup, MM5.2 for the music man-style bridge pickup). However, I think that he's kept the stock (OEM) preamp (4 knob layout: blend, volume, bass treble). What preamp would you kind folks suggest for this particular set of pickups? I'm looking for versatility here - from what I've read it seems that this bass has a naturally modern zing to it, but I'm a sucker for ol' school tones too, so it'd be great to be able to call on those also if need be. I'd like to obviously get the most out of those 'Nordies', so I'm thinking a pre upgrade would possibly be in order. Aguilar? Bartolini? Nordstrand? Leave it alone? Thanks, people!
