Here is a funk guitar lick from a new song I'm working on called BLB Strut. I used a royalty free backing track to demonstrate the lick but the actual song will probably be at a slightly slower tempo and swing a little more. The next couple of licks for guitar were gonna feature will be from this song.
Funk Guitar is all about the rhythm so really listen and focus on the muting and the picking hand. Most of the riff is in 16th notes and the picking hand is generally using alternate picking. Try experimenting with the degree of muting to alter the sound as well. You'll hear in parts of the example a light muting from the left hand will produce harmonics which can add some variation and interest to guitar licks if used appropriately.
