Up for sale, a KGR Harmony Iron 808 overdrive effects pedal, brand new with its box and paperwork. Forged at the Nambu Tekki Foundry in Japan, a source of cast iron teapots since 1848, the hefty alloy enclosure alone is a true work of art, and the Iron 808s circuit is very much in the vein of Ibanez's venerable TS-808 Tube Screamer, while retaining KGR's sonic signature.
The control array includes Volume, Gain, and Tone knobs, while KGR Harmony has made a few refinements to the circuit, removing the in-out buffer, and implementing an inspired choice of op amps. The beating heart of the Iron 808 is a Muses 101 hifi audio IC from New Japan Radio Co. (JRC), the same manufacturer that made the famed 4558 chips prized by fans of early 808s. The high resolution of this specialty op amp gives the pedal a transparent, wide frequency range, and low noise floor that sets it apart from other TS-style boxes. Like other KGR Harmony pedals, the tone of the Iron 808 is best described as huge and clear, with tons of headroom and volume to spare.
