Yeah but I wasnt really aware of that being a thing for "on-on" types. Colour me educated.
I was aware of it for on-off-on types....

For the avoidance of doubt, its this type

It's just a standard DPDT bypass switch

I don't know what you mean by type 2

As far as I was aware the only "types" when it comes to DPDT are in relation to three position lever types??

I posted a vero over at FSB

Here's what I was able to pick off from the drawings that are out there now.

Yep that's the same as I've posted to FSB
So as the doctors say, I concur!

Good to know I was seeing the same stuff as you. I think it sounds pretty rad to be honest.

It's got this bass that is always felt below the fuzz. Kinda cool, definitely different enough to warrant exploring.

What are people thinking about the latest Big Muff out there ?

JHS x EHX have put out a second collaboration, borne out of Bob Myers rotting garage.
The video is worth a watch, mostly to see how endearing Bob is and how unpretentious he is about everything.

Ive breadboarded the circuit as it appeared on the hand written notes and its pretty interesting.
Like a couple of the demo-ers on YT noted (example: https://www.youtube.com/watch?v=F9HjfNVVrS8), its strong on bass side and there is an undercurrent of fatness that I would say is almost omnipresent, with a middy-fuzz on top. You can hear that around 19 mins or so in the video - super interesting.

The sustain is pretty high from the offset, and adds some sizzle and hair as you up it. I wouldnt say the gain or for that matter the volume is in any way lacking. I played around with making the first gain (sustain) stage higher gain and didnt feel it was helpful. Even at max sustain now, you get some motorboarding artefacts - again seen in the video above around 18mins in.

Overall a fun addition to the lore of EHX Big Muff, not sure its that exciting to justify the $250 price point and I would have rather they did something more "out there", but maybe there is a more to come after they test the water with a low-barrier, high selling item like a fuzz/distortion.


Aside:

I decided to make a PCB for myself as an Xmas project because I cant justify buying new pedals right now, and having shared that a few people asked for one. I've therefore made a small pre-order for some standard 3pdt-type boards (rather than my own relay one) for sale. Let me know if you want to grab one.

Just checking in here to make sure firstly that by now everyone that ordered one received their PCBs?

Also, how are people getting on with populating / building this one?

Cool. I am looking forward to seeing how everyone tackles this build.

Hello folks


all PCBs are now spoken for. Thankyou for those who supported that, helps me cover the costs of doing about 8 PCBs on this (!)

I wanted to let you know that I made a rev with a SMD footprint for the LM13700 - so I can confirm that SMD part will work (obviously, with the rev in your hands you would need an adaptor PCB, but it will be viable).

Cheers

Howdy

Thanks for the nice message. I appreciate it a lot.

My bad for any errors. Ive updated the first page now.

As for missing caps let me know specifically what I have mis-labelled there. thanks

It does jump from C21 to C28 with nothing in between

C28 is added to C19 in parallel. The original part of that filter schematic is not on the original MS (hence the bypass toggle) and is indeed lifted ffrom Aleph Null via a datasheet for a PT2399 delay. Is a multiple feedback Low pass filter. The freuqency can be adjusted via C19 - if you want you can just put a 680pF or whatever your preference is up to about 1.5nF ish and forget C28. I found the 680pF can be a tad limited with bass, its grand with guitar. Hence you can mess around. The pads for C28 could also be used to switch in other caps ?

This was hopefully mostly captured in my build notes, towards the end of the BOM doc

"C19 and C29 are in parallel, and approximate a 680p cap. I found it useful try one cap depending on the tone you prefer. Lower (total) values of C19 and C29 will give "peakier" and harsher treble sounds. Higher values will darken the filter. Try anything from 220p up to 2n2 in total. You can simply put a 680pf cap in either position and call it a day 😊"

R7 is 27k

As for the wierd values, its what the schematic called for I guess

Cheers

All boards ordered posted. 1 left.

Yeah totally wild.

Im tempted to even post it up in the Gig Rig facebook lol see what they make of it
