well, thanks for all the feed back. Maybe if I ask a question in a different direction I can get some feed back instead of starying a new thread. My mission is to build a new super hi gain build that beats the Dr. Boogie. And I gotta say. Brians version of EVERYthing seems better than any other type of projects I've buld. And I'm averaging 4 pedals a week. Brian if your reading this "props" to you! Your stuff is great man, I really enjoy building your designs and they come out the most versitile and best sounding w very few mods that I find useless. I've been building vero's at sabrotone and some turn out good. I just attempted a okko dominator clone and I'm very disappointed. Not sure if my build was quite right. I B. Boarded some of these 4049 designs and I ant get what I'm looking for out of it. I've got a ton of O.D.s I've build but I seem to have a hard time tracking down quality "chugga chugga" type stuff. Killswitch engage type of sound. Brians chunk chunk is spot on but I can't play a pedal for too long w/o changing. I've done rats, ocds, transistor, jfet and opamp circuits. I just can't find anything else. What's somthing I can try. Just to explain my level of building I just completed successful philosopher's tone vero. Thanks
