Hi and welcome to the site as well as the California boards.
Bass fishing can be complex yet it can be simple at the same time. You will need to make a small investment in some plastic worms of various colors, sliding weights, dead weights and hooks of various sizes.
I would suggest getting some books to learn from since there are hundreds of aspects to cover and they cannot all be covered in this post.
Water temperature, clarity, outside air temperature, structure, moon phase and barometric pressure all play a key role in what rig you will need to use and how fast of slow you should retrieve it.
Plastic worms (generic term) may consist of Worms, Crawdads, Frogs or even leaches that are all made of plastic.
Colors will vary depending on the water clarity.
Colder water will slow the fish down. Warmer water will increase fish activity as well as surrounding baitfish.
You may need to find some lure that imitate what the Bass are feeding on.
There is no single lure nor color that will be a constant all year. You may want to start your collection off slowly or as your personal budget permits because it will require some investing.
Plastics can come in different sizes and lengths along with the different colors. You may want to take a look at a color chart for the Yamamoto stick baits. There are tons to choose from. Pick some that resemble what is in your area.
You may also want to check out videos on YouTube that can teach you how to do the basic Bass rigs such as Carolina Rig, Texas Rig, Whacky Rig and others. They will teach you how to tie and use them as well as some of the techniques for retrieval.
You may want to learn how to dropshot too. It is a different technique altogether.
We do have a Bass forum here as well. I do believe that some of the riggings are written there. Bass are toys. Gills and Trout are food. There is a fine line between fishing and standing on the shore looking like an Idiot Fast, Free Registration Tell them TubeN2 sent ya
