Reeves has a great reputation for top-notch reproductions of Hiwatt style builds. This amp is modeled after the coveted "Jimmy Page" mod, which has been well known throughout the Hiwatt community since the 70's. It should also be noted this amp has great versatility with the power scaling knob, letting you dial down the output tot reasonable levels, while still driving the tubes. This amp is in fantastic shape, with minimal signs of previous wear.
