The main pivot shaft is of centerless ground 1/2' diameter stainless steel, precision seated though nylon bushings at both ends. Tough long lasting Kevlar cable transmits pedal travel to the controls and is attached by stainless steel springs.The design and development of the Ernie Ball pedals has been a team effort of guitar players and craftspersons within our company. Pedal bodies are an aluminum extrusion rather than a casting resulting in greater strength, uniformity, and smoother surfaces. Clear anodized grain finish insures lasting beauty. Our bodies and shafts are designed to give the player an indefinite service life! Deck mat of non-slip material is impervious to oil, alcohol, and most things you might spill on it. Tough long lasting Kevlar cable transmits pedal travel to the controls and is attached by stainless steel springs. This drive design results in smooth and quiet operation qualities lacking in gear driven models. Cycle tests are made on every pedal to insure perfect operation prior to packaging.
