I love a relic, cant understand the angst - it’s a finish option end of.
Sandberg over all probably do it better than anyone out there and have done consistently for a long period.
Having said that, I tried my own. I took time to work out the height I play my bass, where I play it, how I carry it, how I stash it etc, I even carried it around places with me to simulate wear etc. Then I did this - I quite like it (colour not to everyone’s taste I know!) So i can say this is Very personalised relic, and if I was doing it for someone else I would do the same.
If anyone wants to try their own, happy to share any bits I have learnt.
