Jerry always had cool guitars with the band. . . from that Guild he started out with through the Les Pauls and the Strats and then those incredible Irwin guitars. . . .
One of the ones I like the sounds of the most is the Travis Bean he sometimes used in the Jerry Garcia Band (as well as with the Dead).
They are out there. You also could just get one of the burners with the hard drive. And patch in the VHS to the burner (or the hard drive section, and then from there to the burner) if your machine can hold up long enough to do the transfers. . . .
