Project overview

The Vector Ambient Delay is an easy delay project based on the Mad Professor Deep Blue Delay with a few modifications and improvements added.

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, with similar characteristics to a tape delay unit. It’s equally suited for short slapback effects or longer rhythmic repeats.

Your ears can be the final judge, but even most analog purists 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!

The new version of the Vector removes compatibility with the Rebote 2.5 in favor of a simplified build process. The previous version of the Vector is still available if you want this option.
