Personally, I would only go custom if I couldn’t get it through an production instrument. I find that my tastes change as a player, sometimes even within the time period that a custom bass would take to arrive. Depreciation is generally HORRENDOUS with customs, especially if you’ve gone for something unorthodox (which is possible if it’s something you haven’t found in a production instrument). I like biding my time and waiting for secondhand customs etc which match what I want. It’s a fun game, and if you change your mind and decide to move it on, it generally hasn’t cost you anything to try it out.
