I'm a short scale lover. My Bronco (same body as a Mustang, FWIW) is one of the easiest basses to play. I have a Gretsch 2202 chrome bsoapbar pickup in mine and it sounds great. I think the Mustang and its close relatives are among Fender's better accomplishments.
My '64 EB-0 is lighter, but otherwise similar ergonomically.
My Gretsch Thunderjet is the nicest bass I own, and a great player with beautiful fit & finish.
MY 1970's Univox hollowbody "coily" (335-copy) is a nice period piece even if the staple pickups aren't special. It sounds like a 70's bass with its 20-year-old flats, which is all it needs to do.
And there's my Dean Cabbie bass, yellow with checkerboard sides, which now has dual Gretsch blackface Filtertron pickups. It's a showy crowd-pleaser.
I'm having enough fun with short scales that I don't play my '63 Precision very often.
