Bass pedals rely on the shape of the cam - round or offset, large or small - to give each pedal its characteristic action and feel. Some brands offer more than one shape to cater to the diverse style differences and preferences of the drumming public. Unfortunately, if you want another cam you have to buy a whole new pedal or install a new cam providing you can buy one separately in the first place. Pearl´s PowerShifter Eliminator pedal comes standard with four cams, each with a unique shape and all interchange at the push of a button thus giving the Eliminator the action and feel of four different pedals for the price of one!
