From the post
Here is another trace by evilarsen; Fuzzlord Drone Master. It is essentially a tweaked Rat with a diode selector switch, a switchable twin T notch filter for a mid scoop a la Superfuzz, and an op amp output buffer. There is two versions for this (2019 and 2020) and since they differ quite a bit when it comes to some of the component values. The internal trimpot that sets the depth of the mid scoop was only present in some earlier versions but I decided to include it here since it seems to be an useful feature. Bear in mind that there is quite a volume drop when the switches is in silicon and Scoop mode.
2019 version
2020 version
