From the post
Last layout for a while. This is sort of a hack job, combining a Rat tuned for more low end with a LED/silicon diodes clipping switch. Then the signal is splitted into two signal paths using the Mid Scoop and Mid Boost tone sections from Boss FZ2. Signal is then fed into a treble cut control and an output buffer. *Update 200909* Tweaked it a bit more. A cap to ground at the input solved some noise artifacts without altering the overall sound. Highs control is now a 50kC pot. Oh, and the name was changed to Dronestortion since....it can do some drone metal.
*Update 200912* Final update, I promise. The LED clippers seemed to the driving the following eq op amp stages into clipping resulting in some crackle and a bit harsch decay. Replaced those with normal 1N4148's and for the lower threshold diodes I used germanium diodes, old soviet D9K's but any ge diode will do with V.d. 0,3-0,27.
