Hey all!  I was fishing my local lake last week with a Jig.  I was pitching into laydowns, weeds, etc.  I noticed that I don't notice every bite I get.  The water there is crystal clear, and I started to notice that every once in a while I would pitch the jig next to a fallen log/tree and the bass would suck it in real quick then let it go, almost like holding it in their lips.  I didn't feel a thing! I don't think I would have time for a hook set even if I did feel it. Is there a trick I am missing?  I watch my line every time, and never let the jig fall on slack line.  

Phlourocarbon line and shorter casts.

You want to let the jig fall on a semi slack line. This way it falls straight down. The Phourocarbon line is more sensitive than mono.  

Jig fishing has little to do with worm fishing, in worm fishing you feel the tap-tap when the fish lifts the bait from the bottom, in jig fishing fish seldomly lift the bait, they strike it on the fall. If you are waiting to feel a tap-tap when fishing with jigs by the time you feel it it 's too late.

When fishing with jigs watch your line and be aware of what the bait is doing, if suddenly the bait "dissappears", when you get that strange sensation that you don 't have something tied to the end of the line set the hook immediately.

Switch to a lighter jig with a smaller trailer and let it fall on slack line. You want to make the pitch then strip out some line and let it fall on slack line so that it falls straight. With the lighter jig with the smaller profile the bass will not spit is as fast also use a scent.

Thanks for the quick answers.  I guess I should have said, I use Power Pro when I fish with a jig.  I realize it isn't like worm fishing when you wait for the tap tap.  I guess I need more practice "sensing" the strikes.  I am going to try the scent with a smaller trailer.  Thanks again guys!

When a bass grabs a jig the first tap he has it and you better set the hook the second tap is the fish spitting it out or trying to crush it. You need to be a line watcher so that you can pick up on any line movement. When I fish a jig I do not have direct contact with the jig until I hop or move it. I do this for several reasons but mainly so that the fish will not feel any tension. This also makes sure that the jig reaches the bottom and don't swing to the boat on the fall. Most of the time I either see the line move or just feel resistance when I pick up on the jig.

Watch your line when the jig is falling.  Any sudden movement of the line..swing away!  Sometimes when you are retreiving the jig, you may feel a "mushiness".  That's a bass sucking it in.  Sometimes when retreiving, the line will go slack.  The bass has picked it up and is swimming toward you.  When fishing a jig,  you have to be real attentive and be able to set the hook with catlike reflexes.  When in doubt, set the hook.  Swings are free!

when you get that strange sensation that you don 't have something tied to the end of the line set the hook immediately.

Same if the jig feels "heavy" when you lift it up off the bottom.  It is better to do a swing and a miss than not to swing at all

Remember that the higher you hold your rod tip the more sensitive your rod will be.  Also as whopper-stopper said flouro is more sensitive than mono as well (you also could use braid if you would perfer it but I would stick to flouro if the water is clear as you said).  Good Luck
