# Guitar Pedal take 1? ## Description Guitar pedal starter template based on project by Mark Wu. Includes schematic and PCB layout for basic DIY pedal hardware. This includes two 1/4" jacks (one for input and one for output), a 9V power supply, a 3PDT true bypass wiring setup, and an example potentiometer that can be copy/pasted throughout the circuit. size is a good default size for a 125B enclosure. The headers are meant to be unpopulated so that wires can be soldered to the pads. PCB design rules imported from the JLCPCB 2-layer stackup template. Meant to be used with the 3PDT Breakout Board on my profile. #template ## Project Details - **Owner:** doug-l - **Created:** 1/2/2025 - **Last Updated:** 1/2/2025 - **Visibility:** Public ## Key Components ### J1 — [Pin Header 01x02 2.54mm Vertical](https://www.flux.ai/jharwinbarrozo/pin-header-01x02-254mm-vertical.md) - Part Type: Connector - License: https://creativecommons.org/licenses/by/4.0/ **Pins:** - P1 [pin 1] - P2 [pin 2] ### J2 — [Pin Header 01x02 2.54mm Vertical](https://www.flux.ai/jharwinbarrozo/pin-header-01x02-254mm-vertical.md) - License: https://creativecommons.org/licenses/by/4.0/ - Part Type: Connector **Pins:** - P1 [pin 1] - P2 [pin 2] ### J3 — [Pin Header 01x02 2.54mm Vertical](https://www.flux.ai/jharwinbarrozo/pin-header-01x02-254mm-vertical.md) - Part Type: Connector - License: https://creativecommons.org/licenses/by/4.0/ **Pins:** - P1 [pin 1] - P2 [pin 2] ### J4 — [Pin Socket 01x03 2.54mm Vertical](https://www.flux.ai/adrian95/pin-socket-01x03-254mm-vertical.md) - Part Type: Connector - License: https://creativecommons.org/licenses/by/4.0/ **Pins:** - Pin_1 [pin 1] - Pin_2 [pin 2] - Pin_3 [pin 3] ### J5 — [Pin Socket 01x03 2.54mm Vertical](https://www.flux.ai/adrian95/pin-socket-01x03-254mm-vertical.md) - License: https://creativecommons.org/licenses/by/4.0/ - Part Type: Connector **Pins:** - Pin_1 [pin 1] - Pin_2 [pin 2] - Pin_3 [pin 3] ### LED3 — [LED simulator template](https://www.flux.ai/nico/example-led-simulator-template.md) - Forward Voltage: 1.70V - Datasheet URL: https://page.venkel.com/hubfs/Resources/Datasheets/LEDs/CTL1206FYW1T.pdf - Manufacturer Part Number: CTL1206FYW1T - Part Type: LED **Pins:** - A [pin 2] - K [pin 1] ### LED4 — [LED simulator template](https://www.flux.ai/nico/example-led-simulator-template.md) - Forward Voltage: 1.70V - Manufacturer Part Number: CTL1206FYW1T - Part Type: LED - Datasheet URL: https://page.venkel.com/hubfs/Resources/Datasheets/LEDs/CTL1206FYW1T.pdf **Pins:** - A [pin 2] - K [pin 1] ### SW1 — [Connector 01x06](https://www.flux.ai/jharwinbarrozo/connector-01x06.md) - Part Type: Connector **Pins:** - Pin_1 [pin 1] - Pin_1 [pin 1] - Pin_2 [pin 2] - Pin_3 [pin 3] - Pin_4 [pin 4] - Pin_5 [pin 5] - Pin_6 [pin 6] ### U1 — [TL072CDT](https://www.flux.ai/jecstronic/tl072cdt.md) - Manufacturer Part Number: TL072CDT - Manufacturer Name: STMicroelectronics - Part Type: Operational Amplifier (OP-AMP) - License: https://creativecommons.org/licenses/by/4.0/ - Datasheet URL: https://www.st.com/content/ccc/resource/technical/document/datasheet/bb/4d/19/24/7d/40/48/a6/CD00000490.pdf/files/CD00000490.pdf/jcr:content/translations/en.CD00000490.pdf **Pins:** - -IN 1 [pin 2] - -IN 2 [pin 6] - -VCC [pin 4] - +IN 1 [pin 3] - +IN 2 [pin 5] - +VCC [pin 8] - OUT 1 [pin 7] - OUT 2 [pin 1] *The full schematic, PCB layout, bill of materials, and interactive design are available at [https://www.flux.ai/doug-l/guitar-pedal-take-1](https://www.flux.ai/doug-l/guitar-pedal-take-1).* --- *Generated from [https://www.flux.ai/doug-l/guitar-pedal-take-1](https://www.flux.ai/doug-l/guitar-pedal-take-1)*
