Hi
Does anyone know if the MF-104z Spillover Mod is simply connecting a switch to a jumper inside, or what connection is being bridged/broken on the PCB?
Thanks

It’s more than that or we would have been able to do it with a jack on the back for a remote switch. I love the idea of the mod, I just can not get past that switch mounted like an afterthought on a very expensive pedal. If they would at least mount it on the back…
Ditto. That radio shack switch is a disaster. There’s no way to kick that switch reliably without breaking it. The pedal cost a fortune to begin with. Add $50 to the price tag and do it right; nobody will complain. You either have mucho $$ for it or you spend $200 for a Lexicon and you’re happy.
Me, I’m still saving up for one. Will likely be picking up a Synth.com tub reverb for $136 to hold me over until the year 2011 when I can afford the MF104z.

Perhaps the switch is mounted like this to keep the wiring to a minimum?
If you were clever you could probably use a CMOS IC to do the job of a multi-pole switch and run a cable to an external foot pedal. It might compromise the sound though, especially with a cheap chip.
It also could be cool to control the spillover state e.g. with a gate/LFO/envelope or a comparator (i.e. loud signals trigger the mod etc.).
Hey, if folks are not happy with the switch position it’s easy to mount it on the back. Just ask. It’s custom work anyway, we can put it wherever you want (provided it fits).
As for using a different switch, it has been a problem to find a switch that will fit in the available space. If you have a suggestion for a better switch to use, send me a link and I’ll order some.
Thanks,

Amos, what is the available space and required spec (poles/throws) for the switch?
Some here, although they’re pretty pricey:
Those are all pushbutton switches. Would you rather have this as a pushbutton switch and not a toggle?
I had imagined this was a mod you’d want to leave on all the time, rather than something you’d switch on and off during a performance. But if you are wanting to stomp in and out of spillover mode, then a sturdy pushbutton would make more sense.
Heck if it’s like that, we could put a full-size stomp switch down near the regular active/bypass stomp switch. Would cost more but it’s easy to do it that way. What do you folks think?
Could you just make it where the pushbutton that turns on and off the effect acts as a mode selector or make it where you need to hold the button down for x seconds to activate spillover?
If not then as long as placing the 2 buttons next to one another has no ill affects, such as causing the operator to activate both at once or even activate another device in close proximity, I’d be ok with it.
I’m always a fan of the toe kick like on a hammond exp100f pedal used for turning the leslie on and off. Ok that may be a bit silly, my apologies.
I had to delete my earlier posting as, after reading Amos’ postings again, I finally realized that they never had to put that toggle switch there in the first place. I would have never expected they would just slap a switch on the face plate if it could have been installed elsewhere.
Who’d of thunk it!
well, where would you put it?
Amos,
I kind of like the idea of two stomp switches.
I agree with adding an additional stomp switch.
With an Led indicating the spillover mod is on? How much would that be?
i’d also like a pony, and a box of graham crackers, and a vintage 1950s ray gun with my spillover mod. 
all seriousness, the led and 2nd stomp switch is a cool idea, if implementable it’d be worth doing, provided it wouldn’t crank up the cost too bad.
OK, just had a look at the physical constraints of the pedal. There’s really not room to put a second full-sized stomp switch anywhere near the first one. It’s solid circuit board down there; there is actually a slot cut out for the existing stomp switch.
So, it looks like our options are:
1.) a toggle switch (or maybe a very small stomp switch) up on the panel somewhere near where it is now
2.) a toggle switch on the back of the pedal near the jacks
3.) no switch on the 'fooger, just a new jack on the back that you could plug a remote footswitch like the Moog FS-1 into. Yes we could add an LED to indicate spillover status with this one.
Your thoughts?
I vote for this mounted on the front:
Muuwhahaha!!
SRSLY though, I though lots of people were asking for a stomp switch. Lol, listen to the description from the Moog homepage:
Imagine playing an echo-filled chorus, then switching back to playing a dry sound for the verse, all while your echoes naturally decay, or create infinitely repeating echo soundscapes then solo over them with echo-free.
Sounds like a stomp would be warranted for that case, esp. with a guitar.
Would a LED be too difficult to implement? It needs another switch pole, right?
Um, neither of those examples require the spillover mod to be switched (mod enabled/disabled) during performance.. The switching in those examples is handled with the existing, standard stomp switch. The difference in the examples is the amount of feedback (which is controlled with the front panel knob, expression pedal, or CV input). 
I agree with Moog’s decision that this isn’t something that is likely to be switched a lot by most musicians during a performance. I would always leave it on.. the way the existing stomp switch setup kills the repeats means I don’t use the stomp switch! I’m not really sure where I would prefer the mod switch mounted, but the control panel is an obvious location that should always be accessible, while the back panel might not be accessible in some setups. So having the option to install it anywhere is nice, or to request a custom footswitch setup. I’d personally prefer not to have to use a footswitch for this function, though.
Amos, can you describe how the switch is connected internally for those of us who wish to implement their own solution? Or is the mod more complicated internally that simply switching a jumper or bridging some solder pads?
Thanks!
It is more complicated… there are multiple poles to wire up, traces to cut on the circuit board, and components to de-solder.
Yes, that description on the website is describing a scenario where the spillover is switched on all the time and the player is just using the normal bypass function of the delay (except, with spillover).
Another option would be to hard-wire the spillover so that it is always enabled. You would lose the original bypass function completely in this case. That’s certainly the easiest option.
And yes, I wasn’t imagining that people would toggle the spillover off or on during a performance… I guess you might want to do this between one song and another, maybe…
as for the LED, it would require a third pole if you were using a toggle switch, but for the option where you have a jack connected to a remote foot switch, this would already require some active electronics to be added, and the same active electronics would allow an LED to be switched at the same time, fairly easily.
I think Amos’ idea about wiring a jack in the back for a remote switch is a very good one. It sounds easy to implement, and it’s a really clean solution. It might even make it easy for Moog to implement the mod as a standard feature in future 104s!
But one thing… can the pony still be available as an optional factory mod? 
Edited…
