The Allan Holdsworth Signature OD/Boost was designed along side Allan 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.
