How Do I Make My Guitar Amp Sound 1960's-ish?

I'm 15 and I love 1960's bands like Jefferson Airplane, The Doors, and The Beatles. I want to make my amp sound like it's from that era. (Well, sound more like Jorma Kaukonen or Paul Kantner from Jefferson Airplane, but anyways...) What should I set the Treble, Middle and B to? And, should I use Overdrive or Clean? Thanks :D
