Well I decided that I'm going to try something a little different with one of my basses. I went to a show last night and there was a Led Zeppelin tribute band and a Guns N Roses tribute band playing. The GNR bass player was using a normal MIA P bass, rather than a Fender Jazz Special like Duff always used (and still uses). His tone was pretty close to what the bass in GNR really sounded like so I'm going to use of of my P basses to try and get that unique sound. After doing some searches on this forum and online in general, the only info I can find is that Duff uses SD Hot Stack pickups, which are only available for a Jazz pickup. Since he always uses P/J configurations on his Aerodyne and Fender Jazz Specials, what does he use in the P position? I assume it's a SD as well, but is it more likely a Hot for P bass or a Quarter Pounder? I already have a GK amp which I can make sound like the 800RB with a couple adjustments, so mainly I just need to find the right pickup to stick in there and it should work pretty well for a different sound to mess around with.
