The Custom Jimmy is a faithful recreation of Page's Hiwatt® amp that he used circa 1969 - 1971. It is constructed to the exact same specifications as 1970s British design with Partridge replica transformers, dual channel pre-amp with 4 inputs (2 normal, 2 bright), normal and bright volume, bass, middle, treble, presence and master volume controls. Like all Reeves Amplifiers, the Custom Jimmy is entirely hand assembled using only the finest quality components assembled on a Garolite turret board utilizing "Mil-Spec" wiring techniques.
What makes this amp different from other Hiwatt® circuits of the same period is that is has more gain on tap - more vintage Marshall. And something even more unique is its foot switch volume cut. The amount of volume cut is adjusted by the balance control on the front panel. In other words, the amp can be played with a more aggressive preamp tone (adjusted by the input control) and then switched, via the foot switch, to a less aggressive, more typical cleaner Hiwatt® tone. It works kind of like a two channel amp, but with a single channel.
Power Scaling is a proprietary technology London Power developed to allow the maximum power of an amplifier to be dialed down to whatever level you need. Most Tube amplifiers have a "sweet spot." This occurs when the amplifier's power tubes are pushed into what is known as "clipping," "break-up," or "saturation." The tone and harmonics being produced by the amplifier in this state is why the majority of guitar players prefer vacuum tubes. Unfortunately, in order to get an amplifier into the "sweet spot" the associated louder volume can be very undesirable. Power scaling allows the user to keep the "sweet spot" at any volume!
Unlike power attenuators that are placed between the amplifier and the speakers - causing the amplifier to "cook itself" and seriously shorten tube life. Power Scaling allows the power output stage to be variable from full volume all the way down to bedroom levels while still achieving power tube "break up." Other advantages of Power Scaling are longer tube life at any setting less than maximum. When the Power Scale control is in the minimum position the amplifier is now in standby thus eliminating the need for a standby switch.
