Help me mod my NYC Big Muff? (Tone Bypass/LED)

Post by MrShake » Sun Jun 24, 2018 3:24 pm

(Disclamer: I've done a forum search, I've done a google search, and I'm getting a flood of mixed info. Sorry for what I know is a retread of a topic, but I can't find the info I need in one place, and it might be useful for future idiots like me.)

A recent NPD (post to follow in a few days) has brought me back to the world of Big Muffs. I'm usually a Rat guy. Once I took delivery, I dug a post-2008 NYC RI Big Muff out of my closet and had fun mucking around with it. I have a few other models I like better, but sometimes I forget how fun Big Muffs are. It's a Rev C board, by the way.

I'd like to mod mine for a Tone Bypass footswitch. I can solder-by-numbers, but I can't really read a schematic, and I'm kind of a dummy.

I HAVE a DPDT footswitch in my drawer. As I understand it, the key to the Tone Bypass mod is just taking two components in and out of the circuit, but I dunno what the traditional version of this mod would be. Would the following wiring diagram be correct for the DPDT? [I realize since the components are in parallel, I could just join them up at the ends and send them into a SPST or SPDT (like my Rat/Turbo switches), but I happen to have this one, so I'm stretching out.]

If so, what components apply on the Rev C board? I seem to have read that it was the resistor marked R5 on the board, and possibly the cap marked C8? (the big orange one above R5, its label is obscured in this crappy photo). But I'm not sure if the directions I read were from this board revision.

So, will that DPDT wiring diagram work for the "traditional" Big Muff Tone Bypass, like the switch on my Tone Wicker BM? And if so, which components need to be lifted?


Then...

Let's say, just for hilarity, that I REALLY wanted to add an LED next to the footswitch. Can anybody hit me up with a switch wiring diagram for that on a 3PDT, and maybe any idiot-proofing details? Unsure as to how powering that LED might play into things. I'm not really very experienced with installing switches, and would prefer to rely on the wisdom of experts, rather than my usual trial and error.

Anyway, thanks a bunch. A foot-switchable tone bypass might fully bring me back to the Muff fold, and one with a sweet-ass colored LED indicator light would impress everyone, right?

Sorry for the late bump, but I just found this post and thought I’d share what I know regarding this topic, for the op or anyone else who is still searching.

There a are at least a couple of ways to do this mod. Here are two; I did the second one and it worked really well.

And adding the LED is easy.

I also spent many, many months adding about ten other mods to my NYC Rev C Big Muff. Mid scoop/stock/boost switch, presence/body knobs, switchable emitter resistor mod, switchable LED/no diodes mod, switchable feedback mods, noise gate knob, velcro knob, and a few other component changes. My muff now sounds SO much better (and it was already my favorite pedal), and it is so freaking versatile now. It is like having a pedalboard full of different fuzz pedals.

I can go into way more info if anyone is interested in what I did, what I learned, and where to find out more.
