I use standard in my band and have both of my P-Basses tuned to standard. At home I have my MIA Jazz tuned down a 1/2 step to Eb so I can play along with stuff like SRV, Hendrix, etc. which helps whenever I need to learn a song that isn't in standard tuning. Actually, between that & the strings(Chromes) I think the Jazz sounds pretty cool tuned down.
