Reeves Custom 30 MK II
The Custom 30 MK II incorporates a few changes to the very successful Custom 30 platform.  The first update is to the "Lead Boost". Now it has a variable control on the back of the amplifier to give more flexibility in the amount of boost.  The second update to the boost is that it can be turned on or off from the mini toggle switch on the back of the amp.  Now, if the footswitch is lost, forgotten or broken, one is not stuck in either boost or non-boost mode.  Third change is to the bias configuration; it is now fixed bias, which gives the amp a few more watts and more headroom than the original.

Designed in conjunction with amp guru Mark Stephenson, the Custom 30 is designed for the player that is seeking a wide range of tonal options. It's an amp that can play clean with lush reverb effect and an amp that can lay down the grind for good ol' rock 'n' roll. 

With these parameters in mind we felt that the best power tube to build this amp around was the KT-66 beam tetrode. We wanted to build an amp that has that fat hot fudge sundae texture while still maintaining a touch of Hiwatt inspired vibe. And for good measure we threw in some extras that will be useful to both the bedroom and pro player: Power scaling - the ultimate master volume control.  Foot switchable  reverb and lead boost.

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.

Custom 30 MP3 Audio Clips
The speaker cabinet used is our 2x12 loaded with Vintage Purple speakers. Special thanks to Sonny Moorman for recording the clips.

"...the Reeves Custom 30 ... closely resembles a vintage Hiwatt® but the resemblance doesn't stop there. Inside, you'll find the same military-spec turret board construction, with chassis-mounted pots and tube sockets and right-angle wire runs, along with giant transformers, and impeccable soldering throughout ... with the characteristic bell-like clarity on clean settings, and very British KT-66 grind with the gain turned up it has its own personality as well ... the mids are absolutely wicked, and the lows are tight and punchy ... The Custom 30 makes an excellent low-wattage alternative to vintage Hiwatts®." - Guitar Player magazine
