They say:

True bypass, stereo, analog delay with warmth, fullness and depth, but still with amazing clarity that does not get lost in the mix. Variable time control adjusts delay from 30ms and 600ms. Repeat control varies feedback from slap-back to almost infinite repeat making the pedal well suited for classic, vintage delay sounds.  And the dry and wet signal paths are completely unaltered so your tone remains pure and intact, without thin and brittle sounding repeats. A very organic sounding, delay  without coloration.
