This is just my take on bass life, I'm not telling you what to do.
Nostalgia is expensive. I have one rule - if it's not getting played, it's getting sold. I've sold my first bass. I've sold my "year of birth" bass. It's just stuff. They're just things. There's no mojo, there's no magic, it's just my brain being its usual soft and squidgy self. If it doesn't bring joy, get rid. Basses sitting around idle is a sin - get 'em sold to someone who'll hopefully play it to death.
Or keep it. I'm shrugging now.
