The other day I went to a throw-together gig and struggled to carry a guitar, banjo and fiddle, plus a water bottle. The fiddle had a carrying strap - the banjo and guitar did not. I had my hands full and boy did they get tired!
I started looking into finding straps/attachments for the hard shelled cases and its impossible to find a good D-ring anchor. And I'm not sure I want to drill into my Martin case.
Let me say here - I don't want to mess with soft-shell or padded cases - too easy to crush !!
So I started looking for "Case Covers" - nylon or canvas outer skins for hard shell cases that also have sling and pack-back style straps.
I found them, but boy are they expensive - US $140 to $200!!
Does anyone know of any cheaper alternatives, or other ways to carry hard shell cases ? And yes, I've read the thread on golf carts - they don't work well on stairs!
