Reeves Custom 18 With the Custom 18, you'll find a Plexi-inspired amp unlike anything we have build before. At the heart of this amplifier is 20 watts of fat toneful bliss. The tonal and harmonic characteristics of the cathode-biased EL84 power tubes and 12AX7 preamp tubes are classic Brit. With the addition of separate gain and bright / mid toggle switches, you can tweak your tone or propel the amp into "Big Hair" territory at any volume level.

Power Scaling 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 in the minimum position the amplifier is now in standby thus eliminating the need for a standy switch.
Cut Control This control is unique in that it acts as a tone/presence control in the power amp section allowing the user to cut high frequencies.
Gain Control The gain and Power Scale controls allow you to massage the amplifier into giving you the perfect amount of warmth, breakup and sustain. The separate Power Scale control allows you to keep that killer tone at any level.
