Created the prototype

I found a metal box, then I drilled two holes in the top case and one in the bottom case for the jack. after that, i assembled the circuit and added two batteries, atached the 3pdt switch, and the jack. I tested it and it worked. I also wanted to add a YouTube video, but I can’t edit the project.

3d model

I made this 3d model to show a of how the device will look once it is completely finished, including the DPDT switch, the RGB led, proportions, and size of the box.

some changes anc pcb

i changed the jack in the schematic,

after that i created a pcb(i wont use this because ill mount this on a box so the dpdt will be atached with screws, jack too, and the LED wil be attached to the top with silicone)

and added 3d components

Schematic and some changes

I was thinking that this was so basic and i decided to add one led rgb, one switch, two battery holder, two batterys and i changed the spdt switch for a dpdt switch also i created this schematic and i think that this doesnt need a pcb, just some wires

Basic research

I did some basic research on how can i make a footswitch to change mode in my lt15 amplifier and i found that it is very easy, i just need:

• 1/4 TS jack
• Wire
• Spdt switch
• Metal box

and i learned that the SPDT switch is used to change between two states in my amplifier, and you just need to connect the plug directly to the SPDT switch, there is a example:
