PDF fileBOSS SD-1 Relay Bypass Switch Installation Guide Remove the resistor R23. This will affect the pedal’s bypass circuit so that it will be ready to accept the true-bypass relay switch. Note that the pedal’s bypass system will still work after this. This will the wiring diagrams show a SPDT soft-touch foot switch.
True bypass wiring schemes – stinkfoot
For basic true bypass wiring, you’ll need a DPDT (double pole, double throw) switch. It is basically two SPDT (single pole, double throw) switches side by side. Later, we’ll also delve into the 3PDT (yep, triple pole, double throw) switches, which of course are three SPDT switches operated in unison.
Coda Effects - 3PDT and true bypass wiring
I found out that it was easier for beginners to make a proper true bypass wiring when they fully understand how does it work. The 3PDT Footswitch Before going any further, you have to understand how functions a 3PDT footswitch. The 3PDT stands for "3 poles, double throw". Here is a diagram showing the different possibilities :

3PDT Switch Positive Ground Circuits. Here are some variations of wiring PNP Positive Ground circuits with a 3PDT switch. The basic information about this can be found in Power Switching Article. True Bypass/LED indicator DC Jack For a PNP Positive Ground Circuit with a Negative-tip Power supply; True Bypass/LED indicator DC Jack Input Grounded For a PNP Positive Ground Circuit This is the

True bypass for 1960s-'80s wah-wahs and other effects (diagram 1) 1) Unsolder the wires to the SPDT stock switch, remove it, and install the new 3PDT. 2) Find the input jack terminal "tip," and unsolder and disconnect only the short wire that connects to the circuit input (marked #1 on the circuit board diagram).

PDF fileBeginners are often confused about how one should correctly wire a 3PDT foot-switch for true bypass operation. Most often, this is due to a lack of understanding of how the 3PDT switch operates. Let's fix that. Standard Taiwan 3PDT foot-switch fig.1 Fig.1 shows a bottom view of the 3PDT foot-switch.

True bypass Wiring Diagram– wiring diagram is a simplified standard pictorial representation of an electrical circuit shows the components of the circuit as simplified shapes, and the facility and signal links with the devices. A wiring diagram usually gives guidance more or less the relative slant and bargain of devices and terminals upon the devices, to help in building or servicing the
Switching: Mechanical switches & standard wiring diagrams
In the schematic above you see SW1A and SW1B which make up the 2PDT switch. SW1C is only existent in 3PDT switches to switch the LED to GND. When the effect is OFF: In the True-Bypass state of the switch the Input signal from the Input-Jack (JACK_IN) is directly connected to the Output-Jack (JACK_OUT) via SW1A.
The DIY True Bypass Lesson - Premier Guitar
3. Build yourself a good sounding true bypass box or strip to convert your stompboxes into true bypass devices. The basic idea of a true bypass box is to leave the original stompbox untouched and to add true bypass as a kind of "add on" function; your stompbox is still not true bypass, but you connect it to the true bypass box and this box contains the true bypass function for the stompbox.
