I gig with all 20. They're all the same bass just different colors! I've been trying to collect all 40 or so colors in the same model for several years. Sorry no picture today. I know some would like to see 20 different Am St P's in the same room.
I absolutely love being able to pick from my stable for each show, of which I am fortunate enough to play 3 to 4 shows a week. They all speak to me at different times and I can have the neck off and adjusted in record time since I do the exact same thing so many times. Sometimes it will be a matter of what I'm wearing which sounds crazy but it's not like I ever have a concern about tone. Last weekend I tried a new technique and went around with a flashlight to see who had the most dust. Turned out to be Lipstick Red/Rosewood/White followed by Aquamarine Metallic/Maple/Tort followed by Olympic White/Maple/Mint. There it was, my awesome weekend laid out in dust!
In case you're wondering, yes I've owned a range of other basses over the years, G&L, Fender Jazz basses, Music Man, Charvel, Spector, a pair of Dingwall 5's, BC Rich, Tune, SX and even Westone when they first appeared in '81, so a pretty good variety. But so far nothing satisfies like having a big selection of the exact same pbass.
When I need to go low, instead of a 5, I keep my black one strung BEAD.
OK maybe one pic for now. This one I found showing some racks I made. From left to right you're looking at Hot Rod Red, Purple Metallic, Mystic Blue, Lake Placid Blue, Jade Pearl Metallic, Olympic White.
