Question I just purchased a Ditto and I have a slight issue / inconvenience. As I am colour blind I cant tell the difference between the red and green and in this case the LEDs on your device. Am I able to change the colours or have the coloured diodes replaced to my choice of colours Answer Unfortunately there is no easy solution with the LED colours on the PolyTune units - here is why: The LED we use are mounted unto the main board and can't be exchanged without disassembling the whole pedal and unsoldering the LED's in exchange for another one. The reason why some other products colours can easily be changed is becuase they use a white LED with a coloured plastic lens that slides in front. Unfortunately we do not use this system.
