guitar pedal

A simple footswitch designed to change channels and toggle modes on analog and digital guitar amplifiers. Compatible with most amps that use TS jack switching. I also added a rgb led that shows the state of the switch(red and green)

really cool pedal! please make sure to update your bom to include prices and links for all of your components! even though this is a build review, you still must meet all requirements for a design review! check out https://blueprint.hackclub.com/about/submission-guidelines to make sure you meet all the requirements!!

soldered it, testing and made a video

finally the soldering iron for my hackpad arrived so i assembled all the components in the box and soldered all components, tested it and this is how it ended

Hi! Build reviews are for built projects, please either pay for your project yourself or request a grant and resubmit this project so that you can build it and physically have it in hand, THEN you can re-submit a build review with a video of it working! Sadly, tickets-only projects (where your project is never built) do not exist.

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, painted with black the box, attached 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

Hi! Nice project! Could you please add a rendered 3d image of the PCB with the components and the PCB view in KiCad to your README? additionally, I'd recommend a case for this project, otherwise this would probably be a tier 5. finally, please add a BOM.csv file as well as renaming your CAD folder to PCB! Thanks! :D

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:
