Grubs are tiny lures that can catch big fish, especially big smallmouth bass, but experienced anglers are finding they work just as well on largemouths. They are especially well suited to highland reservoirs lacking extensive cover, where lures with more attention-getting qualities might be ignored by bass.
Grubs are essentially bare jig heads with a soft-plastic body added to the hook. They are best suited for clear water situations. They are most often used as a deep-water lure, but can be fished effectively in shallow water as well.
Grub Weight and Length
In general, the clearer the water and spookier the fish, the lighter the lead head and smaller the grub body you should use. Wind and depth will determine the lead head weight you should use with your grub. In deep water, use the lightest grub you can get away with, because fish tend to hit them while they are falling, not when they are on the bottom. A light grub will take longer to fall and will be exposed to the fish longer. Smallmouth bass prefer shorter grubs while largemouths can be taken on larger ones. Use 1/16 to 1/8 ounce grub head (a ball head - don’t use slider heads) jigs on 3″ grubs and 3/16 to 1/4 ounce jig heads for 5″ grubs. Use spinning gear with a 6 to 6 1/2 foot medium-light to medium action rod and 8-10 pound test line.
Colors
Bass fishermen tend to prefer lighter colors on grubs. White, yellow, chartreuse, “motor oil”, pumpkinseed, salt & pepper and smoke are especially effective. Translucent grubs often have colored flecks or “metal flake” mixed in. This helps reflect light and can increase your catch. In tough conditions, match grub color to water color. In greenish, clear water, try a green grub.
