Hey! Recently got my first 7-string guitar (a boden original 7 trem), and I'm trying to explore chord shapes to use. The tuning I want to use is BEADGBE. I constructed and tried drop 2 and drop 3 chords with the bass on the seventh string but it's missing some high end. So far what I've tried that works the best is taking shell voicings from the 5th(A) string (1-3-7-9) and moving the root down to the 7 string. On the 5th(A) string I now can reach a minor seventh with a bar, so I've been trying replacing the minor 7th that's usually on the G string with sixths. What else could I try? Is there a good resource for exploring new chord shapes? I'm mostly interested in systematic approaches that I can invert without reaching impossible shapes like drop2 and drop 3. Thanks!
