A heavy power fast action rod is a good rod to start with when going after largemouth bass. I prefer a rod that is in one piece at 7' long. The rods that cost more are going to give you better feeling due to the use of better materials. Any rod will due however the ones using carbon blends tend to have the best performance. If you want to build your own rod for a quarter of the price of the 300-600 dollar rods, I suggest going to mudhole.com and buy a kit with an MHX Mag Bass 844 rod. Spinning and Casting rods do not differ, that is your choice. Spinners are easier to use and sometimes better than bait casters. Guides, grips and real seat are your choice, I do recommend silicone carbide guides to help stand up to rough conditions and braided lines.
This set up will give you optimal results while fishing a Carolina rig, jig and pig, and pitching worms or smaller swimbaits. A Carolina rig is as follows.
This technique is widely used for fishing cover so a higher strength line is needed. For bait casting us up to 30 pound braid and spinning set ups no more than 15 pound braid. You can either use a monofilament or fluorocarbon leader, most will use a fluoro close to the same strength or lighter than the main line. Bass are not suspicious of lines or lures, their aggressiveness is what makes them bite. In my experience, bass are the bull in the china shop of fish. They will eat your lure because they want to get rid of it more than they want to eat it. You can also use this set up with the same line strength with or without weights and swivels for a jig and pig set up, or swimbait.
Fish cover from top to bottom and remember to be patient and throw a lure at the same spot multiple times. Bass often take a lot of abuse before eating what you're throwing and are widely known for the best fishing being in the spawn. The reason they are so sought after in the spawn is because they are protecting their nest and become a lot easier to catch. That combined with their fat bellies, spawning bass make great trophy photos and stories. This is simply a beginning to bass fishing. It would take a book to learn most of the information on this subject. Application is key and this will give you a good step in the correct direction.
