Yes.
I came into bass after many years of playing the sax. Generally, wind players will have one instrument (although a tenor player might also have a soprano or a trumpet player might also have a flugelhorn). But more likely than not, it's just the one.
When I got into the bass, I devoured every online forum researching the various basses. Being an ex-audiophile, I know that unless I get I get the very best I can afford (and also something either at the top or near the top tier of whatever it was I was looking to get) I would always itch to upgrade.
So I started buying either boutique or higher end basses in the various forums (all used). My idea and intent was to acquire many basses, then narrow down to "the one".
Unfortunately for both my plan and wallet, each new bass brought a different sound and feel that I ended up liking just as much as the last. It seems each bass I pick up to practice is my current favorite, which really mucks up my plan to get down to just one.
Just yesterday I put away all my basses except the latest entry into the stable. I got this from GC and have two weeks to decide on whether or not it's a keeper. (Who am I kidding...it's a keeper).
But I plan to concentrate on this one for as long as possible (I've already considered taking out one of my other ones but was able to fight the urge). If I can keep the others in their cases or gig bags for any real length of time, then just maybe I can start to sell them off.
Wish me luck.
