The Greer Amps No. 9 is one of our simpler designs. Featuring a 4558 type chip, this pedal utilizes diode clipping, to produce crunchy, fuzzy tones. Some people use this pedal to achieve M*rsh*ll type tone, others use it for light gain, and some like to dime everything out, and bring out the rock face.
This pedal features 3 controls. The top left control (ramp) is the volume control, the middle control (bent line) is a "shelf" control. This control allows the user to control the gain and treble. We refer to it as a "shelf" control, because it pushes both the treble and gain higher, as it is increased. The top right control (jagged waveform) is the gain control, and interacts with the shelf control.
