Multi-Effects Putting two effects in one box almost looks too easy, but you will save a lot of time reading the frequent questions before starting such a project...
I'm building a looper for my pedals to toggle between two effects loops with one switch. I cant use a traditional looper where you need to hit two sitches to turn one loop on and one loop off. Anyway, attached are two drawings...one is a 4PDT switch with grounded inputs for the loop that is being bypassed and the other is a simple 3PDT. I think the 4PDT is true bypass, but I'm uncertain since the bypassed loop is still connected to the circuit via ground, but that wont affect sound in the...
I've almost got all my bits together for my second build, a Green Russian Big Muff, and while I was getting ordering stuff I thought I'd get some of this Van Damme shielded cable stuff, to go from my input to switch to PCB.
Now, when I ordered it, I was just expecting some fancy stranded wire, but this stuff appears to be two insulated wires and an uninsulated wire inside a silver sleeve (which I'm presuming is the shielding), and all wrapped up in orange outer insulation. So should I just use...
Hi,I'm trying to build a passive A/B/Y with 2 LEDs as indicators (only for A,B not a Y LED).
Is this possible using only a 3PDT and a DPDT?
I followed this schematic:
but it seems to be wrong.The way the A+B is wired sends one of them to the ground.The result is only one of the outputs is functional either on A/B mode or in stereo.
How could I rewire this layout to make it function properly?Thanks!
I want to wire up a 3 loop selector that will work like this:
Button 1 selects loop 1 (for now ill jumper it for clean bypass)
Button 2 selects loop 2 (plexi rythm pedal)
Button 3 selects loop 3 (rockbox clone set to singing sustaining lead)
Only one loop will be able to be selected at a time. I want to use it to mimic a three channel amp configuration. I'll put a dirt pedal on loops 2 and 3. I will jump loop 1 for as a clean channel(or utilize it later), 2 will be a pedal set to dirty rythm,...
Hello!
I'm having trouble wiring together a Foxx Tone Machine with a Anthony Leo Fuzz/Swell circuit. Both circuits are assembled on vero board and are taken from the layouts pictured below, by Harald Sabro Bolstad and Jeremy Rouse. The wiring diagram that I found, is a bit confusing to me when I attempt to wire these circuits and switches together. I am a total noob at this, and this is my first attempt at DIY effect pedal tinkering but am confident that I can wire this up successfully with the...
OK - so I've looked around and I can find one or the other, but not one that will let me do both...
I'm looking to make a loop switch to have two loops, a master on/off and a switch to let me choose between series or parallel between the two loops.
Any ideas?
Hello!
i bought a F435A which is a dpdt switch.
i would like to do the millenium circuit because i want the LED to go on when i switch on.
i got this pdf which explains the wiring very well but i have two doubts about it
First: my switch doesn't have any indication in any part so i can't distinguish the lugs. i cant do the wiring without knowing is lug is what. is there any instruction guide ou video that explains how to recognise this lugs?
Hi,
I ma pretty new in the DIY scene and not to familiar in making up schematics and so on.
What I want to do is:
I wanna build a Splitter were I have 1 input and 4 outputs.
Like a Splitter for 1 guitar in 4 amps.
Can somebody help me with a schematic or some advise.
I'm currently playing two separate amp heads into the same mono cabinet (not at the same time). I'm getting tired of having to unplug the speaker wire from the back of the amp every time I want to play the other one.
Can a passive junction box like this be built? If so, could someone draw me a schematic? It would be greatly appreciated.
Again, I know you can't play the amps at the same time. And I don't need any LEDs or a switch. Just two jacks in and one jack out.
I'm in need of lots and lots of wires to make pedals with. I've been experimenting with different gauges but I can't even remember what I liked or disliked. I've seen a lot of people talking about 24 AWG.
I'm on my 3rd build and after 2 really great pedal builds, this one is killing me. I'm making a volume booster (Keeley Katana clone) and have all kinds of problems. While debugging I noticed the 3pdt switch had a very small amount of resistance on the ground lug. Does this mean the switch is faulty? My overall problem with the build is an actual volume decrease when engaged.
Does the 3PDT switch have an orientation? I read somewhere that wiring is based on something like this:
- - - (throw 1)
- - - (common)
- - - (throw 2)
Does this mean that the only requirement is that the pins are wider in the left-right orientation only?
Also, how does the switch work? Does the top left throw only feed to the bottom left throw (etc), thus in effect the 3PDT becomes three on/off combinations combined into one button?
I have a switch / led wiring question that I can't seem to find an answer to. Maybe someone here knows what I'm talking about.
On the pedals I've built I use the 3PDT switch to open and close the led circuit and it works fine... BUT even when there is no instrument cables inserted into the pedal I can still effectively switch the pedal off and on. I noticed on most other pedals this is not the case. They don't seem to come on, or at least the led doesn't come on, unless there's something...
can anyone explain to me how this is done? the best i can figure is that i can use a 4pdt and millenium bypass 2 plus to have an led. is this the best way to do this or is there some other way? If this is the best route can someone please draw a wiring diagram example or try to explain it to me. i would like to be able to still ground the effect input but i am at a loss to how that portion of the circuit works. i have read all the articles on it that i can find and i understand how the led is...
I just hopped on the veroboard train a month ago and while my first couple of builds have been successful, they were also pretty simple. My last two have been a Honey Bee and a Skreddy Lunar Module and both of them don't seem to operate fully the way they should. It ran across my mind today that maybe it is the way I have wired the pots. I seem to want to make everything look very neat and tend to twist my leads so they don't create a rat's nest. It hit me today that doing so is probably...
Does the casing of the footswitch have to be ground? I have finished a treble booster for my board and that is housed in an aliminum box but the pot, switch and 3pdt footswitch are housed on a non conductive surface. Before I Installed it, the booster worked like a charm but now I have installed it, every metalic part of the board makes a sound when I touch it and there is now a ground loop buzz. I've used the audio beavis instructions on wiring a stompbox and I have double checked it. The...
I thank anyone in advance that can help me out. I feel like I'm fairly close and have worked with electronics quite a bit but never a 3PDT.
The image below shows a general set up I have to use for talking points (continued after...)

This image shows the overall wiring situation and I added alphanumeric IDs for each post on the 3PDT switches so we can refer via text for convenience (continued after image...)

Hey, completely new to this lark. Has anyone got an answer, or can anyone point me in the right direction. Basically have some bits and bobs that i want to put together to make a passive a/b switch with a volume control on one of the outputs. Was pretty much following this: and putting a volume control between the switch and output2. I was also just using a dpdt instead of a 3dpdt. But no sound at all when i plug in. Is it just bad wiring or have i got something fundamentally wrong? ~Any help...
I am thinking of building a dual buffer pedal without a switch.
The idea is to use 2 buffers as the first and last in the chain in one box.
so I am thinking of building a pedal with guitar-> into IN_1 -> into buffer1 circuit -> OUT_1 -> through all my pedals-> into IN_2 -> buffer2 circuit -> OUT_2 ->AMP.
The thing I'm worried about is ground loops.
If I connect the DC ground to the buffer1+2 circuits and to all the inputs and all outputs as well.
Hey Stompers,
i'm new here (yeah, I know it sounds a bit gay to say that but i just wanted to excuse myself in advance for asking newbie-type questions) and have decided to build my first pedal (univox superfuzz) based on this verified schematic by ShortScaleMike
i have some questions specific to the pedal that i have asked in the thread, but i'm not sure that thread is even alive anymore, so i thought i'd ask them here.
a) What type of pots (how many pins, etc, i've never bought one...
