Kahler Tremolo System
The Kahler Tremolo System is an electric guitar bridge with a cam operated vibrato arm system. It was invented in 1979 by Gary Kahler and Dave Storey. They shifted their business model to making Golf clubs in the 1990s (mostly due to lower popularity of tremolo use), but are back to bridge manufacturing as of April 2005.
Models and varieties
Cams and saddles are available in several different types, including brass and stainless steel. Stainless steel models were introduced in 1985. Brass cams and saddles have a warmer, more full tone, whereas steel produces a brighter tone with enhanced harmonics. Aluminium cams, announced in 2004 and released in 2005, have what is described as a "bright, growling midrange with super clean harmonics." The 2310, their current OEM model, is the only tremolo to offer the aluminum cam - though parts are interchangeable - and offers brass rollers. Steel rollers can also be used, but, due to increased sustain and harmonics, they are primarily for metal and not preferred for other purposes.
