The ultimate effect pedal, customized based on the Klon Centaur, which Jeff Beck loved until the end. This is a practically unused item, as it was purchased as a spare and only tested for functionality. Includes box and owner's manual. This is The Jeff Archer, a modified version of the highly popular Archer pedal from J. Rockett Audio Designs, a high-end effects pedal brand based in California, USA. The Jeff Archer is based on the Archer model and tailored to the preferences of a world-renowned British rock guitarist. It is modified using rare parts, the same as those incorporated into his actual live tour equipment. This pedal, with its unique overdrive tone and boost function, has captivated the imaginations of players like John Mayer. While based on the Archer, the circuit board has a different sound characteristic due to the use of some different parts. Designed to not be buried in the sound of other instruments, it is a versatile overdrive/clean booster pedal with ample headroom. The controls consist of three knobs: Output, Treble, and Gain. The Gain control allows for a seamless transition from a high-quality clean boost to overdrive. The Output control is also very effective, producing a very powerful and clear sound. Like the popular Archer model, it has a durable metal enclosure and a very compact size.
