It's long overdue, I think. The obvious choice would be the jetglo 350-like looking model, that he often plays, which I understand is an ex 615 from the sixties. So there you have it for the signature model:

1. 350-like body
2. R-tailpiece
3. oven knobs
4. two toasters (my special choice would be RIC mini humbuckers with toaster covers)
5. gold plastic

If RIC would make them, I'd take four or five...
