Solid State Versus Tube Rectifiers | The Gear Mall http://thegearmall.com/product-demos/amplifiers... A rectifier is an electrical device within a tube amplifier that converts alternating current (AC) to direct current (DC), in a process known as rectification. The rectifier is not in the signal chain portion of the amp so your guitar signal doesn’t pass through the rectifier. However, the type of rectifier your amp uses does contribute to your overall sound and tone.
