A Family Medical History Filled With Diabetes, Heart Disease, and Cancer. As a young adult, I witnessed my beloved mother, the rock of our family, battle type 2 diabetes and the complications that come with it. She suffered from kidney failure, vision problems, and heart disease. After 33 years of fighting diabetes, she passed away in April of 2002. I miss her dearly.
Generally speaking, overdrive is the highest gear in the transmission. Overdrive allows the engine to operate at a lower RPM for a given road speed. This allows the vehicle to achieve better fuel efficiency, and often quieter operation on the highway.
Types of Distortion. When talking about distortion, you can usually hear the words overdrive, distortion, fuzz and crunch. They are words describing the type of distortion an amp or an effect gives out. Overdrive is a natural and smooth sound, while a distortion is more rough. Fuzz is a metallic and very rough type of distortion that turns the sound of a guitar into a fuzzy sound. Crunch is not a specific type of distortion, but mild overdrive or distortion.
