This video documents the repair of a beautiful 1964 Fender Blonde Bandmaster that has been giving the owner continuous problems despite numerous professional repair attempts. This provided an excellent opportunity to demonstrate the use of an oscilloscope, as well as common sense, to track down the source of noise originating within an amp circuit. Also, we will see a simple but accurate way to adjust voltages within a pre-amp circuit. To break up the monotony, I have included several special features that will thrill and amaze.
