Fuzzlord Effects FET 120 Overdrive – transistor version
Another one traced by evilarsen. A J FET preamp emulator loosely based on Orange OR120. This one is already verified.
Lell X-Metal
An old russian Boss MT-2 derivate. The eq section and the general topology is pretty close to the original. But cap and resistor values differs quite a lot in most places and the gain control looks like it is borrowed from a Boss DS1.
Mini EVH
Per request. A DIY project posted by Dylan159 at FSB a while back. It is based on Bajaman’s EVH OD but tweaked and simplified. Schematic and more info HERE.
DOD 210 FET Preamp
Here we have a small one, an old J FET booster. Polarity protection diode and power filter cap has been added and the 22k Drain resistor is replaced with 50k trimpot so we can socket and try out a wide range of J FETs.
MI Audio Blue Boy Deluxe Overdrive
Schematic is avaiable HERE. …and by request another layout with with mods by asbestosaurus at FSB. R1 and R2 is the suggested values but they can be tinckered with for more or less overall output.
