Hey Chris
Haven't read the entire thread, so I apologize for any redundancies. I forgot, but what pickup are you using? With guts as I'm sure has been mentioned, Playing any harder than opimum you actually get LESS atack. I see so many young players pulling so hard and getting less sound. I've found that with certain pickups there is a stronger attack and thump. With guts this is crucial. I use the Full Circle which I find has a great sound and bloom, but has much less thump than say, a Gage. I hate the Gage pickup, but it does have a better attack envelope than a FC. Ron Carter used a Barcus with its godawful sound on those late 60's and 70's recordings. Crappy sound, but strong attack. I play Spiro Mittels: my action is medium low, but I've optimized my stroke so that I can pull very hard without bottoming out. I find with the FC that I pull harder to compesate for the softer atack. If I play the Gage, I don't pull as hard for the proper attack, but I hate the sound. With guts when you pull past the optimum point they hit that wall----so most people pull even harder (unconciously) to compensate. So they're pulling harder and getting less thump. I pull a lot harder with he FC than in the studio. Another problem with amplification is that as you turn the amp up after you get to a certain point, your volume may be louder, but you seem to get more diffuse, with less focus. I think this may be due to a couple of things. One, you load the stage and the room too much. I used to always do this.Two, is that your sending more energy from the amp back into the bass and reamplifying that which tends to cause phase anomalies and cancellation. I know the frustration of playing clubs with Tony Williams wannabees. You're playing harder and turning up and whatever you do seems to make matters worse. I've had to mentally readjust where I hear myself onstage down. I find that to my initial perception I'm too soft, but that things are hooking up better with the drummer and the groove is better.
