The secret M117 flanger

[museums]

Should be sold out now  I got it for $100 and shipping+tax

So glad it went to somebody on the forum! And it's a steal of a price. Congrats. It is a fantastic flanger. I wouldn't recommend using the rubber foot control pieces though. The pots are the Achilles's heal of these in that they have plastic shafts, and aren't easily sourced. Using a foot to turn them is a great way to snap them off.

Smallbear stocks a small 3/8" bushing pot if replacements are necessary.

Just got out in the mail today. Choooooooo this thing cooks! 

Came off of the box a bit crusty, but cleans up. Gonna have to hit it with some CRC and get the right pot lube, because it's unpleasant to touch...

I did take off the foot knob covers, but there is is!

I'm sure someone like scruffie would know, but I wonder if there's something going on in the rest of the chip contributing to the better SNR over the 3204, and other products in the line. It definitely sounds smoother than my buddy's BF.

The 3204 and 3004 appear to have a small difference in snr (75db vs 87db). Strange that for the same stage count the 3004 is a 14 pin with six not connected, mimicking the 3204's pin out (if you chopped those six off). More complex inner workings?

edit: no, different voltage reqs, for one thing. Nope. Sad.

12db isn't a small difference. 10db is considered a doubling in volume...

@xvive MN3004 when

The MN3004 is definitely an odd duck. I think it would be more likely that a company like Xvive would make a new SAD1024 before taking on a chip that wasn't really used in guitar effects. That's what makes this version of the M117 so interesting...remember it has two MN3004's in there! It's probably the only guitar effect to ever do that. And it ultimately does sound/feel different than just going with an MN3007, despite the fact it's the same number of stages.
Now if we could just get a schematic...

Now if we could just get a schematic...

I'd have to work up to it myself, having never traced anything more than a FF  I wonder how much it would cost for Robert over at PPCB to trace it... man works miracles. Or Brian. I'd gladly loan mine to either of them. Looks like only a 2-layer to my eyes. Weird grid-style ground plane, like VFE does.
