Boss SD-1 LED Diode concern

[Zombie_Crush]

Hi

Just Modded my SD-1 with a standard red brightness 3mm LED in position D4. Have check orientation which appears to be correct - and the pedal sounds a little louder.
Should the LED light up in this position? Have previously modded the clipping diodes to LED's in my DS-1 and they do.





thanks for your help

I think the LED has a higher forward voltage than whatever diode was in there before (1N914/1N4148 probably), meaning it'll cut the more extreme parts of the signal passing through, meaning a louder output.
The LED's should light up when the signal is getting clipped

FYI: You'll get a lot more responses in the "building a stompbox" section
