I'm building an ASAT style bass and I'm going to need pups very soon. (Build thread in the Lutier's Corner http://www.talkbass.com/forum/f57/4-5-string-asat-ish-bass-builds-1027014/ ) I tend to favor aggressive modern growl over vintage tones. Examples of my favorite sounding basses that I own are: Steinies (active EMG pups, no preamp) Alembics (Alembic pups/pre, Mahogany bodies, mostly maple neck with ebony FB) MM w/2 band preamp Spector (EMG P/J, Hazlab 9v pre, all maple) Generally prefer J over P, but not opposed to PJ. Specs on bass build are Mahogany body, maple neck, katalox (ebony-like) FB. Bolt on. What do you suggest?
