From the post
Got a request for this one. It's the bass version of the Voodoo distortion. It's a very popular bass effect, especially in Japan apparently, but also sounds great with guitar too. A transistor stage at the input pushes a Rat-like LM308 distortion section, followed by a Big Muff-style tone stack and a simple output buffer. Here's the schematic.
