The Fermi surface anisotropy of a pseudo-gap in the spectral weight, caused by superconducting fluctuations or anti-ferromagnetic fluctuations, is calculated for a tight binding band. The importance of the Fermi surface saddle point, or hot spot, is illustrated. A peak-dip-hump structure due to a finite frequency mode, is briefly explored. The connection to high temperature superconducting copper-oxides is discussed.
