From the post
For the blog's 600th layout, here's a new one that didn't take long to get traced. Here's EQD's newest offering, the Westwood Translucent Drive Manipulator. Great for pushing your amp and giving a near clean boost. It features an active 2-band EQ and sounds great on bass as well as guitar.
