One of the all-time classic overdrive/distortion units. Like the Tube Screamer or the MXR Distortion Plus, The Rat lays claim to it's own raunchy sonic territory that no one else can touch. Versatilty is the Rat's strong point. Backed off, the Rat cleans up nicely and breezes through chords with a light crunch while single note solo sing with a hint of grit. Pushed to the max, the Rat goes beyond fuzz with a shred-like sizzle that sustains for days. Tweaking is the key to finding your own take on the Rat sound. The Filter knob is has far reaching possibilities and you can effectively eliminate any hint of low or high-end with a twist in either direction. Our two favorite settings captured the raspy valve-crunch of the early Kinks and the saturated squash of Catherine Wheel with amazing accuracy. Quite a contrasting study in sound, but a nice example of the Rat's amazing range.
