It does sound great and the interaction between controls is super versatile, but I was hoping for a little more bass content. I've adjusted input and rolloff caps to no avail. Currently this is feeding the 2w stereo layout you posted.KDMRhttps://www.blogger.com/profile/12608311647935740479noreply@blogger.comtag:blogger.com,1999:blog-3033460626772757790.post-6188145036138690902015-02-15T20:39:20.403+00:002015-02-15T20:39:20.403+00:00Hi, Paul.

I wrote a longer post but it got eaten when I clocked "Publish"<br /><br />I've tried twice to build this but each time the result has come out the same. VR-1 seems to affect volume, from full to almost no sound. VR-2 has some very very slight effect on Treble. VR-3 doesn't have any perceptible affect at all. I've switched out chips, gone over it with as jeweler's loupe, and even started over to build it again. I can't find an issue or a deviation from your layout. I tried daisy-chaining lug one of all three Pots to ground and then I tried connecting each lug 1 individually to ground, doesn't seen to make a difference. This was all at 9v. I tried it at 15v and got the same results except for a pronounced hum.Bohemian Hhttps://www.blogger.com/profile/09155964862358263643noreply@blogger.com
