From the vendor
Does the world need one more delay pedal? Why, yes, yes it does, and the KDLA is it. So what sets it apart? The modulation can be adjusted from subtle to extreme, mimicking warped vinyl, tape "wow", and other, more subtle, effects. In addition, the delay time can be stretched to over 1500 ms, though it does degrade the delayed signal significantly. It's perfect for that old-school, lo-fi, tape-style delay.
The KDLA is really born out of an amalgamation of the Stalker and the Wobble Box. It utilizes the delay topology from the Stalker (with added feedback control) and a modified version of the Wobble Box LFO that allows for adjustable shape. The plus side of this circuit is that the ES56033 allows for more usable delay times, both shorter and longer, than the ubiquitous PT2399. Aside from that, the overall circuit topology is pretty straightforward.
