I own 7 electric guitars, one bass and a classical, they all fit perfectly on these things. The one that worried me the most was the telecaster cause as you probably know they have a very thin headstock, I thought it would pass through, but no, this thing stops it and holds it quite well.
Another thing that I have noticed with other wall mounts is that sometimes due to an odd non-symmetrical headstock (Stratocaster) the guitar would be held in an awkward position or would be slanted as a result, not the case with this wall mount.
So yes, this has been engineered to work with all shapes, totally recommend.
