I had pretty much the same dilemma a a few years back now when I was toying with the idea of parting company with my trusty old Gibson 1972 SB450L which had been with me since 1974.
I'm pleased to say that the esteemed BassChatters here gathered talked a lot of sense to me which resulted in me keeping it and, I have to say, I have never regretted the decision.
And, as somebody has already said, if you have to "think about" whether to move it on, it is NOT the right decision/
All merely IMHO, naturally!
