The web site explains the change in the gain section if you want to do it yourself. It's just two resistors, but it makes adjusting the gains much easier. If you are getting distortion with sounds that have lots of high frequencies, you need to turn the input down. Sounds with a lot of high frequencies tend to clip a little bit easier (tambourines and crash cymbals, especially), so it's best to set your levels using those sounds in the first place. When the level is set correctly, they do not distort. (I use percussion sounds all the time with no trouble.) On the older units, the LED tends to trick you on this, because it turns red too late. Trust your ears, not the LED. New units have the gain change included, so there's no need to do anything to those. They also have the LED circuit changed so that it turns orange and red at lower levels, which seems to help people get it right.

(Input was guitar >and violin). So maybe they've addressedt this question. New units should be much easier to set correctly. Doing the mod from the website FAQ will make old units equivalent to that. kim ______________________________________________________________________ Kim Flint | Looper's Delight kflint@annihilist.com | http://www.annihilist.com/loop/loop.html http://www.annihilist.com/ | Loopers-Delight-request@annihilist.com
