I was looking at the Diamond Compressor schematic the other day and thought it looked interesting and possibly something that could be simplified – it turns out it can be simplified.  Of course, someone had already done this.  Jump over to the La Revolution Deux for details, AKA Fred Briggs’ blog.  

I used a TL074 instead of a couple of separate opamps for this one.
