Here are some quick mods I do to spinnerbaits when I'm out on the water.
This one is good when your out in the kayak and can't take to many lures.
All you need is a couple different colour spinnerbaits eg: light, dark and natural colour.
Then taking some different types and sizes blades you can change the spinnerbait to suit your needs.
Willow blades to get more depth or to have a faster retrieve and great for the faster water.
Colorado blades for more vibrations and a slower drop.
The inbetweeners like the Magnum, royal willow or indiana blades.
And then the different colours, gold, copper, black nickel and the silver for more flash.
I have been finding the silver great for the clear water.

Here is another quick and easy one.
The rattles you can get for your skirts collars, I use them on the tip of the spinnerbait where you tie your line.
That way if you hit a snag it can make them work along with jigging, also if you don't want them on they are easy to take it off.

Anyone got any more?
