Ric vs. Jazz

I think the fact that Jazz pickups hum cancel when played together had the effect of boosting mids too.

Pickup positions (all of them) impart comb filtering on the signal - a comb filter is a filter where the response goes up and down with frequency - in this case lots of times within the audible range. The comb filter is more complex when there are 2 (or more) pickups involved. For a J setup, the thing you hear most is a dip in the response that's in the mid frequencies - exactly where you can't say; it's different on every string - the E string's first dip is a musical fourth lower than the dip on the A string, and so forth. When you play chords (or muted notes) on a strat in positions 2 or 4, you hear a "quack" - the sound is the result of your ear hearing the filtering/dip change on every string

This comb filter has an interesting phenomenon, though - you can alter the comb filter (and thus the timbre of a note) by playing the same note on a different string - we all know this, which is why we play things in different locations to get different sounds. Another interesting coincidence is that the relative locations of a Jazz neck pickup and a Rick bridge pickup are about a musical fourth apart in the fraction of the string length they are from the bridge. This means, if you play a note on a Jazz bass, with the neck pickup soloed, and the same note on a Ric with the bridge pickup soloed, but play it one string lower (but higher up on the neck), the comb filtering will be the same. Any differences you hear are related to other factors (pickups, wood, fret materials, strings, etc).

Like Willie said, one of each. :thumbsup:
2 of the most distinctive classic designs in electric bassdom.
My current Rick/Jazz choices are what i consider to be “modernised” versions of the classic designs.
Rick 4004 and GL JB2.
