I´m trying to install a LED on the footswitch of my Fender Champ 12.
Footswitch has a single switch with a white and black wiring.
The Champ 12 panel turns a red light when GAIN channel is activated, and voltage on footswitch is 4.12v so I desoldered the white wire, install a red LED with a 100 ohm resistor this path:
white cable > 100R to LED anode > LED cathode to footswitch terminal.
Now if I turn on the GAIN channel the footswitch LED turns on and If I turn off the GAIN channel the LED turns off but the LED on the amp panel never turns off, It stays ON all the time, there´s some bleed on both channels and the GAIN channel has a massive volume drop.
What I´m doing wrong?
Thanks in advance
