These amps are designed and constructed using the basic foundation of a 1960s era Akai or Roberts reel to reel tape recorder. Typical models used includes the Akai M7 and M8 and Roberts 770X. Where practical the original components were used/reused. In most cases the original tubes are still in the amp. The amplifier circuitry has been redesigned to better serve as a guitar amp rather than hi-fi equipment.
There are 2 instruments inputs which share the common volume and tone controls. The 2 inputs however employ separate and different input stage tubes and therefore sound very different. The top input is for the EF86 tube input stage. These tubes were used in 1960s vintage VOX amps, some Dr. Z amps and other boutique amplifiers. The lower input is for a 12ax7 tube input stage. 12ax7s are the most common input tubes in guitar amplifiers such as Fender, Mesa Boogie, and Marshall amps.
Above these inputs is a toggle boost switch. This effect of this switch is an increase in the gain of the center stage of the amplifier. When the amp is powered-up with this switch in the down (off) position a pop may be heard when the switch is initially turned on. This will generally not occur if the switch is in the up (on) position when the amp is initially turned on.
The volume control is located to the right of the input jacks. Unlike most guitar amps which get very loud with the slightest turn of the volume control, this one is designed to make use of a larger amount of its rotation, especially with the boost switch in the down (off) position.
The tone controls are concentric pots, the outer ring is the bass control and the center knob is for adjusting the treble response. These controls are designed to provide an extremely large amount of tonal adjustment. You will find that they also significantly interact with each other, as well as with the volume control, providing the ability to create a large range of tonal profiles. Play around with them as well as with your guitar volume and tone controls, there are no sacred settings.
The tone settings will also affect the point at which the amp starts to overdrive. Harshness, especially at higher gain settings, can usually be reduced by decreasing the bass and treble tone settings.
Play around with all of the controls to find “your sound” and enjoy.
