I was going to limit this to things bass related, but thought it could get interesting if I just left it open despite the fact that the things I'm going to list, are bass related. There are a handful of things that I was pretty big mouthed about 10-15 years ago, that time has changed my opinion about. The topics that keep presenting themselves here on Talkbass most are: Pay to Play - used to get infuriated about it, and at times refused to do it. Today I'm realizing I got to play a lot of awesome shows paying to play, and bands that I know who never had any issues with it - are still playing the most awesome venues around. Active and passive basses - always played active basses because I felt the tonal options and tweak-ability were absolutely necessary. Finding out only in the past couple of years that with most passive basses, those tonal options aren't necessary. My passive basses sit well in the mix no matter how I dial in the tone. Fender - Hate, hate, hated Fender. Don't love them yet as I still think they're hit or miss, but my #2 most played bass these days is my Jazz. And ah hem... uhh.... feel like the Fonz trying to say I was wrrooo.... wr.... OK... Weight - I used to be very vocal about people just manning up, hitting the gym, and not crying over a 2 lb. difference in weight. That's what I did, dammit! And while I still do that, I have started to experience some lower back pain at times (which I am determined to and WILL heal). Running around a stage with a 7 lb bass for 2 hours is much, MUCH, different than running around with a 9 lb bass if yer back is messing with you. There. I fessed up. It's a bit freeing, and humbling at the same time . Your turn.
