Hola, hace tiempo que no escribo en el foro y hoy a al mañana me acordaba de este famoso pedal y de la gran cantidad de versiones que existen. Es por eso que abro este hilo, para elegir el que mas fanáticos tenga y hacer una pcb fácil, cómoda y con los potes en la placa porque no me gustan los cables, jajaj.
Triangle (first edition)
PNP transistors, FS36999
In the Singlecoil, the schematic is wrong, it says 10k pots when it's 100k, and the diodes and the 50n capacitor are reversed.
Triangle (second edition)
NPN transistors, 2N5133
Diodes and capacitor (50n) are placed reversed respect to the other triangle.
There's a capacitor missing, parallel to 390k resistor in the first transistor.
First resistor 3k3.
Missing resistor to ground in the second transistor.
Resistors from collector (or emiter in this case) to ground change in the first transistors, 820, 150 y 820 instead of 100, 100 y 100.
Ram's Head
PNP transistors, 2N5087
Violet Ram's Head
Transistors, NPN FS36999
Interesting, it's almost the same circuit as the third edition except that capacitors are 0.1u instead of 1u, which makes it less bassy, and a change on the tone section (the resistor to ground is 39k instead of 100k, wich makes it more mid-scooped, but not as much as the Ram's Head.
Also, in the second transistor, the resistor to +9V is 10k instead of 15k.
Third edition
Transistors, NPN 2N5088
Almost for sure, the missing resistor (Ra) is 100k. This is also the GGG version, though it changes capacitors from 1u to 0.1u.
American Reissue
Closer to the russian versions. Not as dark sounding.
Civil War Russian
Green Russian
Current russian reissue
Differences with the green russian are insignificant, just three resistor values. The one that sets the minimum sustain passes from 1k in the green russian to 10k in the black reissue. The 20k resistor in the tonestack is now 22k, and the resistor to ground in the last trannie was 2k and now is 2k7.
