Charles Michael Parks, Jr.

Charles Michael Parks, Jr.uses an amputated 1972 Rickenbacker 4001 for most of the night. The guy he bought it from was left-handed and so he had chopped off the upper bout, slashed off some of the headstock, and flipped it around to play lefty. So Parks got the bass super cheap, had set it up to play right handed, reworked the electronics, shaved the bridge and moved it back, and then outfitted it for the proper stereo jack. It usually has D'Addario and Co. Half Round (.050–.105) strings on it.

In the video by Premier Guitar titled "All Them Witches Rig Rundown [2026]," at the 36:43 mark, Charles Michael Parks, Jr. showcases his dad's 60's Fender Precision Bass, which functions as a backup instrument and is included in his guitar rig.
