I'm thinkin' of puttin' together a "Warmoth Special". The pup'll be a `51 P-bass type. AFAIK there are 5 on the market - 2 from RioGrande and 3 from Seymour Duncan. TB'r The_Sound_of_The_Police mentioned that he put a RioGrande in his project. I'm wonderin', is there any drastic difference in tone? Goin' by the S/D description, I'm leanin' towards the ¼ Pounder given the sound I'm goin' for, i.e., "sensitivity" and "lots of midrange". I sent Bass Player mag an email suggestin' a "shootout" given the resurgence of the popularity (Sting, J/P Jones, etc.). Next issue fer' sure! . Here's what catalog info I could find... S/D ( Tone Chart: http://www.seymourduncan.com/tonechart.html#bass ) "Vintage for Single Coil P-Bass® SCPB-1 -- When Leo Fender brought out the Precision Bass® in the early '50s, the pickup looked much like the Telecaster® guitar pickup, with black fiberboard flatwork and black string wrapped around the coil. The SCPB-1 looks just like the original vintage pickup, down to the smallest detail and gives you the same bright sound. Pickup cover included." "Hot for Single Coil P-Bass® SCPB-2 -- Stronger magnets with more coil windings give you higher output with more punch and a thicker bottom-end than the vintage model. Like nearly all our pickups, this direct replacement can be installed with no modification to the instrument." "Quarter-Pound for Single Coil P-Bass® SCPB-3 -- Quarter-inch wide magnetic pole pieces give you more sensitivity than the Hot (SCPB-2) model. The full tonal response covers a very strong bottom end for a solid responsive sound with lots of midrange." RioGrande "In Spanish Muy Grande means Very Big. Enough said!" "The old basses were very cool but limited in tone. The expanded body and volume of this Tallboy replacement pickup brings the sound up to par with its six string counterparts. "
