Using the Rigs:
With the rigs above, you don't just cast out into the weeds and reel in. You have to have fun with it. Pretend your Texas or Carolina rig is a bug that is exploring the weeds. Let it sink to the bottom, let it slide over logs and Lily Pads, let it pull through thick grass. Make your rig look like a living creature that is searching for food among the grasses and weeds. Let the bass think it's an unsuspecting food item. The more natural you make your rig act, the greater chance you will get a strike.
Don't cast where you think the bass will be. Cast a little past the area and bring your lure through the area. Sometimes if you cast and land right on top of a bass, it will spook the bass. Then again, if the bass are really feeding, the bass might hit your lure right away.
In some lakes, the bass will go deep and hide down in the deep weeds. I have seen some really big Largemouth Bass being caught by people who were Walleye fishing. If you are not getting them along the shore, try pulling a Texas Rig through the thick weeds or drift over a deep weed bed with a spinner and a long dangling worm.
Be very quiet: Most times when you see people catch fish on bass fishing TV shows, it's all staged. They have several boats out fishing and when a bass is caught, they go back to the main boat and take the bass out of the live well and put it on the host's line where they pretend to catch the bass again. The bass is already on their line when they set the hook. The host who is pretending to reel in a new fish is usually screaming out brand names of fishing gear companies while bringing in the fish. In reality, largemouth bass are a shallow fish and hyper sensitive to sounds. Talking or accidentally kicking something in the boat will spook the bass and they may quit feeding for hours. You have to be very quiet.
When they are not hitting rigs or lures:
Sometimes you just have to use live bait. As a kid, I always hunted Largemouth Bass along the shore with a hook, float and a bucket of minnows. Worms, small frogs and crayfish work good but I think Chub, Sucker or Shinner minnows are the best. Get a medium size hook and a small float. Have the float about 6 to 12 inches up the line (depending how deep it is) and hook your minnow on. Hook the minnow in the mouth. Come up through the bottom and top lip. Don't hook the minnow in the back because they die twice as fast and predatory fish always hit the head of the minnow, which means hooking the minnow through the lips means better hook set. You should also try to use barbless hooks when using live bait.
Just paddle or use your electric motor and move along the shore. Cast your minnow at the edge of the grass or lily pads and just wait. The very best spot is under a big log or under a floating mass of cattails (bullrushes). When you get a big mass of cattails coming out from the shore, the edges are usually floating because the wave actions keeps the roots of the cattails from planting in the bottom. Some of the biggest bass I have ever caught were hiding under these cattails.
Cast your minnow to the edge and wait. A bass might look at a minnow for 5 minutes before taking it. If you think nothing is going to happen, then slowly bring the minnow back to you. Sometimes the bass hit when the minnow starts moving away. There is one rule that's always true. The slower your float goes under and the slower the bass swims away with your minnow, the bigger he is. So if you see your minnow racing around, then it's probably a perch, crappy or a rock bass.
Pro Bass Fisherman use heavy 15 to 30-pound test because they are speed fishing. They are not there to enjoy the day or the fight of the fish. They want to bring the fish in as fast as possible so they can win money. If you are fishing bass for enjoyment, then use low-visibility 8-pound test line. You will get more hits, you can cast farther and it's ten times more fun bringing the fish in. With 15 to 30-pound test line, you might as well be bringing in an old boot.
