I've tried playing in drop D to play a song with a lower D chord that the one you can do with standard tuning, and it has pros and cons.
One of the cons is that the E string take some time to stay in tune after the drop D when it's back to E. To avoid this, I tried something weird: a partial capo holding every string but the E string. In standard tuning, it simulates a drop D but transposed +2.
It's actually more practical than a drop D because you can still do G chords and any barred chord just the way you would in standard tuning. (Playing a F# is a little harder in drop D than normal)
I don't think I've seen this anywhere, can it be damaging for the guitar? It's really helpful and I'm suspecting the reason I've never seen it before is because I shouldn't be doing it at all. I'm guessing the pressure might be uneven on the neck or something.
