What value LED is used in FU-3 Footswitch?

[ChrisYoung]

I would like to change a few of the LED's in my Mark IV and my FU-3 footswitch. Green for clean, Yellow for channel 2, Red for channel 3.
And maybe a blue for the EQ or Loop buttons.
May also, change the same LED's in the Mark IV itself.
Does anyone know what the values are for the Mark IV & Footswitch LED's?


Thank you!

There are no values to LEDs. Completely interchangeable with each other. Just keep the polarity straight and you're in good shape.

There are not values, but there are sizes. 5mm seems to be the most common, and I believe that is what is in the Mesa footswitches. You will also need to put a resistor between the voltage and the positive terminal of the LED. The value for that resistor can vary depending on the LED, but a higher value resistor will make for a dimmer LED. There are calculators out on the internet to determine the value of resistor you should use but generally 1K to 4.7K should be fine.

Thank you gentlemen.
I wondered what the specific spec was for the stock LED's to just do a direct swap out.
Like 3.5v 5mm, etc.
