Schematic/Wiring for A/B + C Loop Switcher?

Thank you so much! Can't wait to build it this weekend. You are a beast!

Whipped this up for Phil, so thought I'd share it here, too.
Order switcher added between loops A and B, C stays put at the end of the chain and Phil's going with a Rail-GND so kept that:




You could add a jumper as indicated for any or all of the channels, thus grounding the loop's input when in bypass — probably isn't needed, but might solve a problem, or 'cause one!

Tôi nghĩ ra điều này cho Phil nên muốn chia sẻ ở đây.
Bộ chuyển mạch lệnh được thêm vào giữa các vòng A và B, C vẫn giữ nguyên ở cuối chuỗi và Phil sẽ sử dụng Rail-GND nên giữ nguyên như vậy:

Bạn có thể thêm một jumper như đã chỉ định cho bất kỳ hoặc tất cả các kênh, do đó nối đất đầu vào của vòng lặp khi bỏ qua — có thể không cần thiết, nhưng có thể giải quyết được vấn đề hoặc gây ra vấn đề!

Can you wire a A or B/C and B or C loop switcher. Basically it a ABC switch with send and return. An A or B or C loop switcher

Can you wire a A or B/C and B or C loop switcher.

Chắc chắn rồi.

Đó chỉ là bản sao của looper trong Bài đăng số 23, bạn có thể sử dụng cùng một sơ đồ và chỉ cần đặt "C" trước "A&B"; hiệu quả là...

C trở thành A,
A trở thành B,
B trở thành C.

Basically it a ABC switch with send and return. An A or B or C loop switcher

Với tôi, bạn đã hỏi hai câu hỏi riêng biệt, đó là lý do tại sao tôi chia bài đăng của bạn. Đối với nửa sau...

Tôi nghĩ cách tốt nhất để thực hiện một bộ chuyển mạch vòng lặp "A hoặc B hoặc C" chỉ có một vòng lặp hoạt động tại một thời điểm là sử dụng Mô-đun bỏ qua rơle thông minh của Robert.

Hello @Feral Feline , it would be possibile to transform the "C-BYPASS" of this schematic to a "MASTER BYPASS"?
My goal is to have one switch for bypass the entire pedal, and one switch for select A send/return loop or B send/return loop.

And I'm wondering if the IN connector should be mono or stereo, sorry I'm pretty new to this.

Thank you for you help.

Do you want to get rid of the C loop?

 

[danielegaudenzi]

yeah loop C isn't necessary

I don’t have a way to draw a diagram at the moment. You basically keep the A/B switch the same, but the two green wires would both go to the top left and right pins on the master bypass switch. The middle left and right pins of the master bypass go to in and out and the bottom two are connected. The middle column of pins is for the status LED, like the C switch.

No problemo...

EDIT: OOOPSSS
Just sub in jacks for the INs / OUTs:

This answers questions I didnt realize I had. Great stuff.

I drew this trying to follow the suggestions, starting from the original schematic, I don't know if it would work:



@Feral Feline thank you for your additional scheme, i will try it

Ahhh I just realised you're looking for an A/B looper, and what I thought you wanted was an Order-Switcher.
I haven't slept, and as usual I screw up when I'm sleep-deprived.

I've made a new diagram for the order-switcher with jacks, you can find it here.

The diagram you've got above there is good-to-go for an A/B switcher.

I'll fix up my other post and add my A/B anyway...




[EDIT]:
Forumite the mighty JCPST introduced me to another 4PDT method of an A/B either-or that grounds the inputs of the not-in-use loop, so I thought I'd ground the Master-Bypass as well...

 

[Feral Feline]

I just re-read a post by MDC earlier in the thread noting that STAR-GROUNDING may be a better method as daisy-chaining is more susceptible to Ground-Loops.

SO, that was a good reminder to do Star-Grounding when building these contraptions; alas, I haven't been depicting Star-Grounding in these diagrams — so, adjust to taste. If you have any weird noise or hum or whatever...

... try STAR-GROUNDING !
