Just some general tips...
1. Fish stealthily! This is very important in highly pressured waters.
2. Fish the most out of the way areas you can reach in that boat. 75%+ of anglers fish from shore, especially on smaller waters. Reaching those secluded spots can make a difference.
3. The majority of fisherman are throwing spinnerbaits, Berkley Power Worms, or the occasion Rat-L-Trap. Go to your local Wally World or bait shop and ask what the best selling lures are. Then don't fish those. Instead of the spinnerbait, throw a swimming jig. In place of the 7" curl-tail worm, try a 4" finesse worm, or dropshotting. As a substitute for the Rat-L-Trap, find a good one-knocker bait such as the Xcalibur One Knocker, or the Rapala Clackin' Rap. The more "exotic" your presentation, the less likely the bass have seen it.
4. Drop your line size as low as you feel comfortable.
5. Don't be afraid to hit the middle of the nastiest cover. Most fisherman don't want to lose their lure, and therefore label these spots as unfishable. They aren't, you just have to know how to go in and get the fish.
6. Fish it during week days, if possible. Get there earlier than anyone else, and hit the prime spots then.
