removing the buffer from my CRYBABY

[yeeshkul]

Hello guys i have 2 questions considering my original Crybaby. I wanna remove the input buffer+DPDT and rework the circuit so it is a bit closer to VOX.
My Crybaby is GCB-95 and i bought it new in about 1995.

1. Shall i remove the 68k resistor right behind the buffer as well (it doesn't exist at VOX schematics and i am not completely sure what is this attenuation for ...)
2. The inductor doesn't look like typical GCB-95 inductor but more like the older model with a screw in the centre that pokes up from the top of the plastic cover.
I am not sure about the inductance, is there any simple way to measure it? Do i have to remove the inductor from the circuit to measure it?
I have read somewhere that these were about 500mH while the new ones are 600mH ...

There are also some changes at my circuit comparing the schematics posted - 2.2M resistor in parallel with the 22p cap (the very input), 100n cap in parallel with 200u cap ...

Thank you

thank you i have read it, but it doesn't answer my questions
but thanks

Do you mean that 68k input resistor? Here is some info about that in the middle of this page. http://homepage.ntlworld.com/s.castledine/greenfuz/wah.html

those inductors were all over the map, too. i think youll get closer to home in some of the newer inductors, really.

but a dmm that measures inductance will do the trick! no need to remove, just find the two "hot" posts.
