Hi, first post here...and it's an easy noob question for y'all.

I want to build a simple A/B audio switchbox that has two 3.5mm stereo inputs and a single 3.5mm stereo output. I want to build something that lets me use one set of Boston Acoustics PC speakers + sub-woffer with separate inputs from my Windows 7 PC and the headphone out jack on my small 19 HDTV. Obviously, for my needs I'll be using *either* A or B but never both at the same time.

I want to use a small enclosure and 3PDT switch...

what is the best way to make electronical simulation of 7P2T switch?

controlled with ordinary DPDT.........with FET-s....or other way

can somebody post some schematic?

thanks

borislav :thumbsup

Hi folks.

I'm new to the site but have had great fun building a colorsound one knob fuzz as found on this site.It works great and havnt heard that vintage fuzz sound for years.Could anyone help me with wiring in a foot-switch? I have a 3PDT switch with 9-pins! not sure how to wire it between the 2 jack sockets. many thanks

steve

Ok, so I put together the Paia Tube Sound Fuzz kit yesterday, and was fairly happy with the results, but I was dissapointed in not having a foot switch, and I wanted to add an LED, so I've been looking at this diagram:

I have the LED, I have a 47k resistor, but when I went and picked up a stereo input jack from Ratshack, I noticed the fucking thing has FOUR soldering lugs..Its a three-conductor component.

So which ones do I use..?

Am I using the wrong kind of jack?

:headpop: :help:...

makes wiring a switch a no-brainer!

I am building a triple loop true-bypass looper. I managed to fit it into a 1590BB enclosure, so I am pretty darn proud of myself.. hehehe..

I bought one of these from LoopMaster years ago, and decided to build a couple of small ones for my backup rig. When I looked at his circuit he had different resistor values for his pulldown resistors. 4 loops with a tuner mute, he had:

18k - Tuner mute - Blue
1k - Loop 1 - Amber
1.1k - Loop 2 - Green
1.1k - Loop 3 - Green
1k - Loop 4 - Amber

It looks...

Hi all! This may be useful to some of you!
Enjoy!
:D

Can I add a true bypass or any other mods to my black Russian big muff? The switch it dead on mine and I bought a 3pdt and that has 9 posts, the original has 6. A true bypass would be nice, the tone sucks when distortion isn't engaged.

Hi everybody first post ever! Im totally new to building effects. have just built some germanium treble boosters using a pcb from musikding.de. they sound great, but there is a pop everytime i engage the pedal. ive looked at ways of fixing this. thought id ask all the experts out there what they think!?? cheers ben :)

Just wondering which type people prefer and why.

I'm getting ready to build my first pedal. It's a simple fuzz box. I'm guessing the input and output should both be mono. Is that right? I appreciate answers to this obviously newbie question. Thanks.

As you all know the 9 series aren't true BP with there fet system. just wondering if anyone has had any ideas to true bypass them because they can be really noisy.i was thinking a 3 way 3 pole switch but how would you wirer that suck in??

Thanks Tom

Just notice my supa tonebender uses 2 mono jacks.

The ground travels through the 2 sleeve pins and someone has mutilated the contacts as such

As you can see if a jack is inserted the two contacts meet and the ground is connected. Crafty.... cheap bastards!!!. Doesn't look like the sturdiest connection but would probably work at a pinch if you were out of stereo jacks.

Someone must have seen this kind of thing before, but it was news to me.

I've been thinking pedalboard where one can change signal order with somekind of switch panel.
Let's say we have 3 pedals in a board, board has mounted cables for pedals like:
pedal1 in, pedal1 out
pedal2 in, pedal2 out
pedal3 in, pedal3 out

then there this panel where you can choose where pedal1 output should go, something like this:
guitar signal goes to pedal1 in
pedal1 out goes to pedal 3 in
pedal3 out goes to pedal2 in
pedal2 out goes to amp

that way, one can layout pedals whatever...

Hi

I rewired and rehoused my Blue Box. I had noise issues so I decided to forget about diode and do the true bypass with DPDT. I was barely shocked when I played a note and heard that bypass is NOISY. All the time I hear kinda of fast clicks. They sound like a slow oscillator.

Connections are correct...
Please help me. I've tried even guitar cable with ground...

Could it be fault of one octave mod? (wire!)

Regards
Luke

Cant seem to figure it out, I cloned a Boss DC-2 and the thing sounds amazing but I cant figure out how to bypass this thing with a 3PDT switch and still have the LED work, I dont need it to be TB, just to work, any help would be appreciated. I dislike boss's bypass so I built it without hoping to do true bypass or a buffer on a seperate small board.

hey guys-

my buddy has a KOT with a bad pcb mounted 3PDT switch. i've removed the excess solder with braid, but am having a tough time getting it out. i really don't want to fuck up this pedal as it's not mine, so i'm kind of leery in handling it too hard. anyone have any suggestions for removing this stubborn bastard?

oh yeah- i've got to have it done by tommorow!

Hello all,

Thought I would ask some questions about rotary switches. I have these:

For the application I'm using it for at the moment, I need 4 positions. I've adjusted the little washer with a tab so it now has 4 positions. My only question is how the 4 positions correspond to the outer 12 and inner 3 contacts now. I'm building the Stringringer and McMeat projects right now. The understanding is not as important for the Stringringer project, though, as the rotaries are PCB mounted. For the...

wanna make 3 channel preamp, and got problem with momentary switch.
any one have info to make one?

hi!
first of all, I am really new in this, so don't mind my lack of basic knowledge..

I have a problem with 3dpt, I can't find it anywhere! I live in Belgrade, Serbia, and here they have no idea when I ask them about 3dpt in stores, most of them never hear of it, and at the moment I can't order it online or anything (long story).

Is there a way to build the pedal with SPDT and something else?

Is it incredibly important what gauge I use? My order arrived from Smallbear today (ordered the 24th!), and I received a spool of wire that is noticeably smaller than the leftovers from the Monte Allums OD-308.

I was planning on using the leftovers (white) for the jacks and switch and LED, and the Smallbear stuff (purple) for the control pots. Is there going to be any problem? I assume everything sold by Smallbear is usable in stompboxes, but I just thought I'd ask.

Another question is...

Since I'm new to this and would love to build this could someone help a newbie with a BOR layout vero or otherwise that shows the switching with LED?? Thanks!
