yes, it looks odd but if you look at the schematic at Kitrae's Big Muff page there is clearly a 2,2k resistor in line with the power supply. SThe schematic is at the bottom in this link. http://www.bigmuffpage.com/Big_Muff_Pi_versions_schematics_part2.html
Thank you ,,, I see from big muff schematics ,, the 2k2 is correct .. confused with scotchy diode on photo .... tell me one last think ,, I complete the board and it’s sound amazing but it’s noisie .. the big muffs make noise without put input jack ?
Hi, it's commonly used for polarity protection, it's placed on the 9V trace... But in this design, D5 isn't present. If you look at other designs on the site, you'll see a diode of this type or a 1N00X before the 9V line.
Hold the switch so that you are looking at the bottom and the lugs are facing like this: _ _ _ _ _ _ _ _ _ They are numbered like this: 1 4 7 2 5 8 3 6 9
Hi! With this scheme, I must link Frist 6 pins of footswitch 3pd, remaining 7,8 and 9 pins. I'l put Pin 8 to Jack Out, 7 to PCB out( volume) and 9 to input instruments linked to the PCB input? If I want to put a diode led? I like to know what Switch numbers are
The "Skreddy" method for 3PDT bypass wiring (using the numbering system that I posted) that Tom linked to goes like this: 1: LED cathode (short leg) 2+3+6: ground 4+9: 1/4" input jack tip 5: board input 7: board output 8: 1/4" output jack tip.
I know that it is scary to try and do something like this for the first time because you want to get it right. But building this way means making LOTS of mistakes. As soon as you get started making mistakes, you will teach yourself how to do it right. Good luck!
Thanks Chris! Your help is much appreciated, iknow what you say, butt I am a person who gets demoralized easily 😁, I know the mistakes helps, next time a'l try to make myself! A big 🤗
There are different methods to wiring your bypass switch. A popular method is the Skreddy method. https://tagboardeffects.blogspot.com/2012/02/offboard-wiring.html
Good morning fuzzhead ... I think the 2k2 resistor after 9volts is wrong ,,, must the D5 there . Correctly ?

ReplyDeleteYes, Big Muffs can be noisy depending on component values and transistors. V6's and late V3's is said to be the more noiser variants.

ReplyDeleteThat sounds graet Marios!
DeleteHi Guys, D5 what is it for? I don't find it

ReplyDeleteThanks i'l put in +9V line
DeleteHi! There's some scheme about 3pt footswitch? I don't understand the numbering, online they are contradictory
ReplyDeleteThanks! 🙏
Hold the switch so that you are looking at the bottom and the lugs are facing like this:

They are numbered like this:
1 4 7
2 5 8
3 6 9
Nice, 👍 thanks

DeleteA big 🤗
A big Hug
DeleteIf you can find the datasheet to your switch, it will tell you the pin numbering?
ReplyDeleteThere's some difference, here the numbers are different https://share.google/4haiPDt5uqUsrX4GK

Thanks for the suggestion, I'll take a look !
