You still need the isolating transformer. Your source is the guitar.

If it's guitar effects that you're interested in, check out: http://www.geofex.com/
Most of their tube schematics are for amps but I think I remember some for pre-amp stomp boxes using 12AX7's.

These sites have some good information on tube circuit design for newbie-types:

I'm starting my first tube project, too, but luckily there are lots of places on the web for info. DIYAudio is definitely one of the best for answers to questions.
