Hey Devnulljp! I've seen you over on Stickist. Excited to see you on the journey. For me, getting started I used Bob Culbertson's videos and Greg Howard's book. Of course, neither of those are for dual bass recip, so I'm not totally sure how well they'd work (it's a fascinating way to set up btw, but I'm "standard" on mine). One thing I can suggest - get in touch with Greg. He gives lessons (via Skype or something), and he would be happy to even do a one off session with you, answer questions, point you towards stuff. He's cool. You can find his contact info on Stickist.
I'll take this opportunity to post a gratuitous photo...
