Just working on a quick (or so I thought) "Tube Screamer on Steroids" mod to my SD-1. Sounds good but the I went to replace the LED with a 5mm green and noticed it wasn't very bright. I lowered the limiting resistor value (R30) without much luck (went down from 3.9k to 1.0k). Then I looked at the package and saw "30 Mcd". I was pretty sure this meant millicandela as Megacandella is not a measurement. So I swapped in a yellow 5mm LED (http://www.taydaelectronics.com/leds/round-leds/5mm-leds/yellow/led-5mm-yellow.html) with little to no difference. Starting to think something is up here. Shouldn't a LED with a rating of 2000-3000 mcd be brighter than the stock Boss? I thought I was going to have to INCREASE the limiting resistor.
