Will my heavy action bass tackle work for muskie fishing?

Oh, it will work, technically. You sure could catch a Muskie, but I don’t recommend it. You will lose a percentage of fish due to the light gear, and some of the large Muskie baits … well, you won’t even be able to throw them effectively. If you are serious about giving it a good effort, get yourself a quality Muskie sized baitcasting combo like my Signature Series combos from Bass Pro Shops. Otherwise you will really be handicapped. Stock up on some quality leaders, a couple of good bucktails, a couple of jerkbaits, and a couple of cranks. That will be a good way to get you started. Also, hire a reputable guide your first time or two out. You will learn much faster and more than pay for their fee in making the proper selections for tackle.
