Open Discussion / Re: The secret M117 flanger

Sounded like a separate modulation underneath the main modulation to my ears.
Maybe they have one 4013/14013 running as divided by 2 from the first clock?

I have noticed this sound from my pedal as well. There is a subtle 2nd modulation effect taking place in the background. It would be amazing to be able to mod the clocks to really take advantage of the fact this is basically two flangers running simultaneously! Again, the unobtanium schematic for this version is the key.

My guess is because of the MN3004's piss poor clock to gain ratio and the fact there's two almost certainly in series what you're both actually hearing is basically a tremolo along with the flanger.

If someone posts some decent gut shots it shouldn't be too hard to trace and confirm seeing as we already have the 117 schematic.

Looking at the Peavey DSC-4 dual clock chorus. It has 4 controls, 2x speed and 2x depth controls for each "clock". It really only has one clock, but 2x LFOs(072s) that look to be combined into a comparator(U3-B)and fed into the 3101. I would think this could confuse or glitch the 3101 but it makes for a very lush chorus.
Perhaps something similar is occuring in the MXR. Or it is somehow creating a decade of the LFO?

There are a bunch of dual LFO choruses from that era and in practice the clock just sees a different pattern of rising and falling voltages over time than with a single LFO. The LFO with the higher depth control generally has more influence over the movement of the overall voltage. With both depth controls in the middle you can get interesting non-linear LFO movement.

IIRC the Peavey is a little different because it has two different LFO shapes.

Did anyone consider the possibility that maybe it's just being used for something very dull, like switching? For that fancy new LED?

I appreciate it guys and I haven't quit. I just need to find my motivation again, somehow.

I'll be in Hville in a couple of hours. I'll swing by and Rochambeau ya if that helps.

A good beating might be needed. I don't mean that in a perverted way, lol.

What a tease :p
