I'd prefer to get such a "controversial" trace correct. I have no interest in the circuit itself.

Re: Freekish Blues- Alpha Drive
Or could it be that I'm checking for a non-standard pin arrangement based on some peculiarity?

Re: Freekish Blues- Alpha Drive
Can you use the diode function on your multimeter to measure them? Just put the leads across Q2 (important) in both directions and post the readings. Thanks again!

Can you post the full code from the face of the 2N7000? Thanks.

Re: Freekish Blues- Alpha Drive
That can't be right then. Looks like 310K to me and that would pretty much align with the parallel reading. Thanks.Shawnee wrote:It looks like a brown, brown, black, brown so I think it IS a 1.1K Aaron. It is reading 247K in parallel with the outside legs on a 1M pot.

What's that resistor across the "OD" potentiometer looking like to everyone else?

Re: Freekish Blues- Alpha Drive
It is an OCD, I've traced it in my head. Thought that was already established. I'll draw the schematic just so there can be no confusion. Would like better pictures of the lower MOSFET section, though.

If the OP posts the capacitor values, I'll make a list of the mods.

Re: Freekish Blues- Alpha Drive
If I was trying to make an OCD clone, and wanted it to sound slightly different, I'd give it an asymmetrical clipping option - this could be the use for the extra transistor. Your average Boutique Boob wouldn't bother with a bypass buffer - particularly when it wouldn't pass the "does-it-pass-...

Re: Freekish Blues- Alpha Drive
However - it's got a TPDT footswitch, so the LED is going to be switched by one of the poles. That's why there's an SM resistor there feeding the LED. Sure, I'm not blind or ignorant, those things are quite obvious. It's just that there are some peculiarities about the bypass scheme and my only oth...

Re: Freekish Blues- Alpha Drive
It's not unlikely at all, actually. That switch changes the corner frequency of the low-pass filter/tone control at the output of the circuit.

Re: Freekish Blues- Alpha Drive
I'm sure the extra MOSFET is just a Millenium Bypass.

Is the strip at the bottom even covering anything?
