[QUOTE="Niccolai:288371"]Nope, the reason you get the squeeling feedback is your guitar pickups interfere with your amp, like when you aim a mic at the pa speaker. The reason you get buzz is because your pickups are natrally loud pickups (EMGs are known for being noiseless). Since this system doesn't go between your pickups and amp and doesn't involve any modification to your amp and the wires don't even come into contact with your system (except for the ground) theres no possable way it could feedback even if you tried to make it. The only side effect of the system is it drains your batteries quicker then normal (EMGs you can leave plugged in for a roughly 4 weeks straight day and night before they need to be replaced) this system only cuts battery life down about 4-8 hours off of that 4 weeks depending on the brightness of the LEDs you use. Generally, each pickup requires about 80 microamps (uA), EQ circuit requirements vary widely but are higher than pickups. For your reference, a standard 9 volt alkaline battery provides 580 milliAmpHours (mAh) of power. That means that it will provide 580 milliAmps for 1 hour or 1 milliamp for 580 hours. There are 1000 uA per mA. You can figure the approximate battery life of any setup by adding up the individual power requirements, then dividing 580,000 by this total. Here's an example: 1 - EMG-81 = 80 uA 2 - EMG-SV = 220 uA*2 = 440 uA 1 - EXG = 410 uA -------- Total required = 930 uA Total life = 580,000 uAh/ 930 uA = 623 hours If you left your guitar plugged in day and night, the battery should still last a month. Under normal playing conditions, you would probably be looking at changing the battery twice a year. Of course, you should treat these numbers conservatively and not try to drain every last uA out. But yea, the lighting system will only shorten that 623 hours by about 8 hours tops. [/QUOTE]
