pedal switch

[fosterinc]

let me refraise, i want to replace my micro switch on my effects pedal with any toggle switch like the mxr pedals have anyone have any ideas? thanks

I didn't catch your first post, but Google may be your best friend for that question. There are effects forums and many places that document that pretty well. Look for "True Bypass". Maybe include the name of the effect you want to modify to get a specific hit on your model. Finding a schematic of your model will be necessary eventually. If you can follow it, separating the switching components from the signal path is pretty straight forward in most cases. If you Goolge for a schematic of your model, you will probably also get a hit on a boutique version that has the wiring changes already.

Can you be a little more specific? What micro switch on what pedal and what toggle on the MXR are you talking about?

I don't think he's talking about true bypassing the pedal as he is talking about replacing a switch with a TOGGLE switch. Unless he wants to turn the pedal on/off by hand everytime or he meant to write PUSHBUTTON switch.

Hi Fosterinc
I'm guessing you are meaning replacing one of those momentary push switches (like in a mouse) with a switch that toggles from one state to another. The momentary switch usually controls electronic circuitry which
behaves like a toggle switch ie flip flop circuit .
There have been requests for this before
Here is one thread

and here is another vaguely related

sorry i did mean push button the 3pdt switch.one the links you gave me was close, the boss pedal with the new mounted switch. same basic idea just not sure how to to wire it

[Bloodbath]

So you want to true bypass a pedal with a 3pdt switch? We would need to know what pedal you want to true bypass.

[fosterinc]

it is a behringer dd400 delay or it can be any true bypass switch what i am doing is transferring the guts to a metal box so the original switch will not work

[Bloodbath]

I would need a schematic.

It sounds like all he wants is a panel mount type momentary SPST. They may be purchased at any electronics supply.

It sounds to me like he is re-housing the pedal and wanting to true bypass it. I could be wrong as he isn't giving up too much information.

He has us all guessing.

We get you are re-housing your pedal in metal enclosure. Are you wanting to true bypass it with a pushbutton switch? If not, can you be more specific about what you want to do?

Well as it's a Behringer I don't think a schematic will be forthcoming.
I doubt even the authorized agents would have a copy of the schematic 'cause it would be cheaper to replace than a min service charge.
The main criticism I have heard about these pedals is the case.
However to make them that affordable they had to make that compromise
I guess.
So I can see where you are coming from and no doubt won't be the first or last to do this "gut" transplant.
The two most practical ways I can see are:-

1. As guitician said you could buy a panel mount type momentary SPST
I have seen them in some products that look like a traditional footswitch.
Haven't a clue who stocks them but first you will need to determine if it is normally closed or normally open.
So when you step on it does it make or break a circuit ?
Measure the original with a multimeter and then press on it and see if it opens or shuts.
That's the easiest solution keeping the original LED indicator.

2.Wire in one of those 3 pole double throw footswitch's using one for switching the LED which you can wire independently back to the supply,
bearing in mind you will need a suitable dropping resistor.
The direct out will only work when the pedal is engaged.
Wire it as a true bypass (ugg) (it may click) the two sockets wired to the center pins etc. (there is a ton of info on this on the web) and the original wires that went to the delay in and out (forget direct) to the appropriate pins on the switch - the opposite throw ones are joined so the signal would go straight through.
The trick here is to make the pedal permantly on .
The easy way to do it would be to mount a small momentary switch where it won't get bumped..
maybe a small hole in the side with the switch mounted on a bracket so its just below the outside surface.
Then each time you power it up you will have to turn it on (poke it with a blunt object ! )so then the new 3 pole switch choses between the already on pedal or the straight through wiring.

There is a diagram on this page that may be helpful

I agree. A schematic isn't probably going to happen.

I also agree that finding a momentary switch would be the easiest possible solution.

Here are some possibilities at Smallbear:

yeah sorry about not being more clear. but yes i want to rehouse the behringer pedal and make it true bypass. everything looks like not too much of a prob but the switch. thanks for the replies i will look at the momentary switch possibility yeah and the behringer no go on the schematics wont give them up. i had bought a few behringer pedals to get me buy, and now slowly replacing them with home built and a few brand names so now i have these and there not worth much on resale cause there so cheap new, i thought of givivng them a little upgrade and a new casing anywat thanks again
