The Allan Holdsworth Signature OD/Boost was designed with Allan’s input to create a very versatile tool. This pedal gives you a very mild OD and a very “tweakable” boost section that allows for different EQ emphasis. By hitting the OD with the boost you can get some pretty scorching gain! Allan needed a pedal to combat backlines yet still achieve his signature sound and feel. This pedal turned out better than we expected and has proven to be a mainstay on our personal boards.
