OK, I rebuilt this thing from the ground up. Did it on a perf board (was on the Radio Shack Board). Did it real slow and checked each solder as I did it. I still have a problem. When the Tone is turned all the way up it kind of sputters. Kinda like there's a loose connection somewhere (intermitant). However with the Tone all the way off, it sounds better. You can get a real sweet spot with the Tone all the way down, Gain rolled off about 50%, Grit swithch on and Volume all the way up. Also, I don't think it's as loud as it should be. I have changed out the Tone switch, cap on the Tone pot and retouched every solder joint. I have also checked continutity of all gound connections. I have changed out the amp and transistor. I have check, double checked and triple checked the layout. I checked everything I can think of. Can someone help?
