I'm not sure I agree.
I don't actually want a Shergold; actually I do, but an original UK one. I love the whole Shergold story; a range of basses and guitars that were a good-value, high-quality alternative to expensive American or poor quality instruments. I love the association with Joy Division / New Order / UK Subs / Buzzcocks etc. But you are correct. If I want a Shergold, I could just buy one.
When I suggested the Shergold, what I really meant to say was a short scale, E-e bass with string spacing between that of a "normal" six sting bass, and the Fender bass VI. I just said Shergold as a shortcut. I'm not sure that I could convert that Shergold to a VI, but I could buy a Fender VI, Eastwood Sidejack, or a...
Name any bass, and I'm sure we could come up with something close.
I'd argue that my suggestion fits in perfectly with the Eastwood philosophy - quirky instruments with a cult following, that are no longer available.
How about a 4005?
I need a biscuit.
