I got a new Rocktron wah pedal in today and had to adjust the switch height, it was taking a whole lot of weight to cut it on. The switch had the LED attached to it and in the process I damaged the LED. Most likely bent the leads where they entered the resin encapsulation and broke the connection to the diode itself. Not the best way to attach the LED but it was working when I got it. It was a 3mm blue LED and I got to looking around for a replacement and found an automatic blinking RGB LED with similar specs to a blue LED and thought it would be cool to try. Have any of you guys tried this with success and is there anything I should watch out for? The following link is to the specs if you're interested, http://www.superbrightleds.com/specs/rgb-acc-spec.htm , I've ordered a couple to try out. If it works it should be VERY noticeable that the wah is on.
