Remember that crankbaits are lures that are designed to be retrieved fast.  You use crankbaits when the fish are very active and willing to chase fast moving baits for a great distance if necessary.
 
When Largemouth bass are holding in deep water and are not very active you need to change your approach.  It is too deep to use a spinnerbait and inactive

Largemouth bass will not chase a fast moving crankbait.  This is where the jig and pig combo comes into focus.  A jig and pig combo consists of three components:
 
1)     A weighted jig head of some form of color.  I like to select a color that contrasts with the body of the jig rather than matches it.  I like to select a jig that has a hook of an appropriate size for the size of fish I am angling for.

2)     A body of some sort.  The body of a jig can be a plastic twister tail, a formed body made of colored hair or a plastic worm.  My only consideration is that the color of the body must contrast with the color of the jig head.

3)     A piece of pork rind attached to the hook that acts as a trailer to the combo bait.
 
Jigs are best fished very slowly.  I like to cast the bait into the target area and employ a retrieve that consists of a twitch of the rod that allows the bait to jump a few feet from the bottom.  I then allow the jig to sink back down, watching closely for a strike as it begins its descent.  When fishing for inactive Largemouth Bass you often need to place the bait right under their nose.
