Scott Devine usually has a great point to say but spends too long to get to said point. Which depending on what mood I'm in, I quite like his ramblings.
My thoughts on his point though would be as below.
People don't need expensive/boutique/handmade/custom bass. Expensive gear won't make bad players sound good but I do feel they will make a good player sound better. I could get away with what I play on any bass but quite frankly, I enjoy playing my basses. I am inspired to play more often when I'm using an instrument that I like. I've had many basses in the last 3 years and when I've had one that I really like I've definitely improved as a player.
Play whatever the hell you like but keep in mind that you are the one making the noises.
