Here in the Midwest walleyes move shallow....sometimes as little as 1 foot of water...to feed. In the streams....a floating / shallow minnowbait can work well.
For the bass, you will have to slow your presentation down so they can use their lateral line to feel the vibrations / hone in on your lure. Try popper-type lures....or maybe a spinnerbait with double Colorado blades....lots of thump with those. You could also try one of the newer SMALL double cowgirl inline spinners.
For muskie...an old technique popularized by Joe Bucher is "row trolling"...just using oars. Here too....gotta slow down the presentation.
http://www.joebucheroutdoors.com/And as mentioned....larger / shallow running crankbaits with rattles. The problem with suspenders at night is that they don't make any noise / vibrations when at rest. That doesn't mean they can't work....just gotta work them slow.
Tom made some good points. In general...the night bite doesn't happen all night long...maybe 2 hours at the longest for these species. Figuring out WHEN it is happening is the toughest part.
