From the vendor

The Vector Delay is a DIY workalike of the Mad Professor Deep Blue Delay. You can also build a Tonepad Rebote 2.5 using this PCB with some parts substitutions.

The circuit is based around the PT2399 delay chip. While the PT2399 is technically digital, it doesn’t have the sterile sound characteristics associated with modern digital delays, but is instead much warmer and analog-voiced.

Your ears can be the final judge, but even most analog purists will give high praise to this circuit. With the overall complexity being much lower and the cost of parts being far cheaper than a BBD-based delay, you owe it to yourself to try this one before jumping straight into a true analog delay!
