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.

Saw a horse, so I expected a Klon, right? Well, it's a Rat, and a really good one. On top of the classic 3-knob interface, there's a Silicon/LED blend, which is really helpful. The silicon side (classic Rat) is more compressed, the LED (Turbo Rat) is more mid-focused. The volume of the LED side is quite louder, so you have to adjust the volume every time you experiment with the blend. Tall box, silent foot-switch, top-mounted jack in/out. 5 stars.
