From the vendor

If you haven't noticed yet, I kind of like reverb projects. This is for a few reasons. First, when I was first looking to design projects for the DIY community, I noticed that there were very few reverb projects out there, with virtually all of them using the Belton brick or FV-1. There's nothing wrong with those parts, but they are pricey and, as of late, can be hard to get. I have since done a lot of research into reverbs, the Belton Brick, and other designs. The Wishing Well represents my 5th DIY reverb design, none of which use FV-1 or the Belton brick.

Another reason I like reverb projects is that they are challenging. I don't do very much at all with boost/OD/drive circuits, because everyone and their dog does a million and many sound very similar. I like a good challenge, and reverb is a challenging type of effect.
