nope.. I have my hands full as it is.... I knew a guy that added one bass string to the rest of the 6 on a wide neck... sounded full in a noisy bar, nothing fancy.... but there's some wicked 7 string pickers around these days.... Lenny was an innovator in this stlye as well......

I knew another picker, out in the country... he used to give lessons to the locals... new student, older cat, showed up with a guitar, but it only had 2 strings... buddy thought it was a joke.. he said, "Where's the other strings?"... the student was serious, saying "Well, show me somethin, on these two and if I get good enough I'll get more strings !"...... true story from Calumet, Quebec...
