Walrus Audio Iron Horse V3

This pedal is characterized by tight bass, aggressive mids and sweetly crisp treble. Gain range on LED clipping side goes from discreetly crunchy to searingly saturated, but this pedal has a smoother midrange than many of the type. On the silicon side the mids are practically scooped out, the extra saturation and compression taking the pedal dangerously close to all-out fuzz territory. LED clipping is so much bigger and louder than the silicon. You have to adjust the volume to compensate for every twist of the Si/LED blend knob. Stacks well with other OD pedals. Great sustain.
