It's a pedal for those who need a vintage style flanger, that can produce both a slight subtle modulation and a roaming flange. Very versatile pedal, mixes well with overdrive and distortion pedals i have. Built quiality is also really nice, it's built like a tank. It's my second ThorpyFX pedal and i can highly recommend it.
Only two drawbacks: pedal is a bit big in size, wish it was smaller; also it's price is high, but you get a good product for it.
