I have an OHSC case (G&G) for my Orion 5 for sale. A potential buyer asked me if his Epic 4 would fit in it. Does anyone know if it would and how custom fitting these cases are? Thanks for any help.

The Epic has sort of a triangular upper horn. If the case follows the inner curve of the upper horn of the Orion, then an Epic won't fit. The rest of the shape should be pretty close, I would think.

We use the same case for Orion and Epic basses for new shipments. The foam inside is a memory foam, so if your case was used for an Orion, it's formed to match that shape more closely, but it should still be a good fit for an Epic.
