Master Volume Mods for Marshall and Fender Style Tube Amps

In this vid we'll talk about 4 types of Master Volume controls outlined in Ken Fischer's excellent "Trainwreck Pages" and analyze the pros and cons of each type before installing one and testing it with a Gibson Les Paul in a SUPER LOUD, vintage 1971 Marshall Model 1959 Super Lead 100. The mod we choose is a post-phase-inverter-master-volume (PPIMV) control, which will allow the player to get thick crunch and juicy lead tones at bedroom volume levels. This information will also be useful for installing master volume controls in many amps such as Fender, Traynor, Ampeg, and Gibson.
