Front Panel Controls and Their Functions
Input Jack(s):
Input jack(s), are 1/4" phone plugs, designed for 1-Meg impedance, guitar-level
signal. This input will readily accept pedals/effects without any loss in performance.
The design of the Clean Machine amplifier is quite flexible, so we first suggest
exploring its performance without any effects or pedals initially.
Gain Control:
The gain control sets the overall gain for the amplifier. There is no master volume.
Depending on the guitar, pickups and whether you are using pedals or not, this
control may be set anywhere on its rotation. Although this amp is called the Clean
Machine, it can be driven into overload at high volumes. It is capable of clean output
up to clipping, and usually produces more than its listed power.
Brite Switch:
The Brite switch operates with the gain control/and is active over about ½ of the
input gain control range. From ‘0’ to about midway, it provides a boost to highs, and
the effect of the switch decreases beyond the halfway point on the gain control
rotation.
Deep Switch:
The deep switch shifts the overall tonality of the amplifier, increasing the low
Frequencies. This is often useful for single-coil guitars, which sometimes need
A low-frequency boost, or for jazz players who prefer the added warmth.
EQ Switch:
The EQ switch alters the operation of the tone controls. The upper position is
Will be the highest gain, and a brighter equalization. In the downward
Setting, the tone is a more neutral/linear tone. All tone controls work in both
Modes, however their range and depth of operation is changed.
High Control:
The High control serves 2 functions: (IN)-it adjusts high frequency spectrum. (OUT)
the High control engages the mid-boost. This shifts the range of the high control
downward, to include more midrange. All tone controls still operate, however the
tone will be fatter.
Mid Control:
The Mid control serves 2 functions: (IN) Acts to adjust mid frequencies. (OUT)
changes the frequency of the mid boost. This warms the overall midrange tone and
this can also fatten sound for Single coil pickups.
Low Control:
This control adjusts the low spectrum of the amp. Pulling it alters the pivot
(frequency) point of both the mid and low controls for greater tonal range.
