I'm definitely a Pbass player over a Jazz bass. Have owned more pbasses, than i've played jazz basses. Only a handful of Jazz shaped basses held their own & sounded good to me (a long forgotten copy my friend used to own, had a heavy weight & chunky profiled neck. Ibanez black Eagle just had thunderous tones, again weight was awesome. & a squier Affinity i had at one point in time, modded with a push/pull for series/parallel wiring. Sold it to a friend who needed a bass).
Pbasses aren't the first basses i ever saw (my dad had either taped this performance, or somehow found Kiss live in San Fransisco 1973-74. I saw Gene's Grabber before seeing any FSO). But Dee Dee Ramone got me into the whole Pbass thing, & just the overwhelming use of it to this day, had me hooked from the first time i picked one up. Now, i own 7 soon to be 9 (a fretless & another maple/maple fretted neck variety) to complete the array of pbass tones. I can gel with a jazz bass, but really depends. I'd rather have a pbass over a jazz any day of the week.
