This guy has been on the bench for months and months. In part because I'm indecisive but mostly because I was way out of my comfort zone. It has been a great project to learn and get into new territory.

I first started with the DBA Sound Saw. I liked the idea of it but wanted to make it suit my playing rather that whatever it is Oliver is doing. It ended up being an input buffer and gain stage into the two filters and then the DBA specific reverse beta output. The input is a Hyper Fuzz building block and the output is the DBA, however both are heavily modded. The two notch filters cover a lot of ground. I used and to figure out what was happening. I don't think I am ever going to understand LTSpice so If someone wants to model it that would be cool. (y)The notch filters kept changing for months trying to find the right sound I was poking around for in the dark.

Anyway, it's finally done and I am very please with the sound. It's almost always on now.
