Base Wood C has a cool, rough wood feature. Take a Cloud 2, plug it in the Greyscale input of a Non-Uniform Blur Greyscale node. Plug a Dirt (Dirt 1 is good) into the Blur Map input. Crank up the intensity to 30-50, Anisotropy to 1, Asymmetry to 1, Angle to whatever, Samples to 16, and Blades to 3 to max. It’s a simple, quick way of getting that noisy/slightly rectangular wood grain.
