The Iron Horse is our take on a classic
distortion circuit that’s thick, punchy,
riffy, and rowdy. With the help of the
Si/LED knob and wide range of the
distortion knob, this true bypass, high­gain behemoth can be finely tuned for
clear overdriven sounds or let the reigns

loose for a full-on distorted onslaught.

LEVEL – Controls the output level.

TONE – Allows specific adjustment of high-end/treble frequencies.
Turn clockwise to increase high/treble frequencies and counterclockwise to
decrease high/treble frequencies.

DISTORTION – Adjusts the distortion output. Turn clockwise to increase the
amount of distortion. As it is increased, the signal becomes louder, thicker,
and more distorted. Turn counterclockwise to decrease the amount of
distortion.

Si/LED KNOB – Blend between Silicon and LED clipping. When the knob
is set to the left, the distorted signal will be using Silicon clipping diodes
adding in a high amount of compression. Rotating the knob to the right
will bring in LED clipping and a smaller amount of compression. Putting the
knob at noon will blend between the two using different ratios of the Silicon
and LED clipping diodes for more complex clipping sounds.

Note: Since the Si/LED knob is changing the internal gain and clipping style,
the other controls will behave slightly differently as well. You will need to
use the volume knob to adjust the overall output up or down depending on
where you have the knob set.
