I went to the local music store today to find a 76 P-bass, and what a bass it was. Ash body in natural with aftermarket tortoise pickguard, but the big thing was the pickups had been swapped for Di Marzios (the ones with the white pickup covers). Also, another Di Marzio P was added to the bridge position. Ugly as heck with the double P and the white covers, but the tone was awesome! Volume and tone knobs, 3 way pickup switch, and another 2-way switch that we can't figure out. It's almost some kind of boost, all I know is one way give a clear, defined and tight sound a la J bass, while the other way sounds middier and powerful. Come to think of it it might have been a parallel/series switch. Anyways, this bass was alive! Powerful passive tone with help from the ash body, no doubt. Front pickup only = pure P-bass, while back pickup is a nasal version of the P tone (although sounds good, think of a soloed J bridge pickup, but P form). However both pickups on gives a very strong sound similar to 2 humbuckers (such as a G&L or Bongo or something). Very cool, tight P bass sound, great feel. Only problem, 1000$ CDN. I don't have that kind of money (I'm saving it for a fretless). But wow!
