Beginner project trouble
« on: October 19, 2006, 09:47:30 PM »
I built the boost pedal and i have it working correctly, but I have a problem when I plug it into a tube amp.  When I plug it into a tube amp I get loud "ungrounded" (I know what it sounds like because I have wired a bunch of guitars) sound and I have my pedal grounded correctly.  With the Pot, the input and outpur jack, and the negative of the battery snap wired together after the 47k resistor.  So my question is, What could be wrong?

If it's really loud. then somehow you have wired it incorrectly and there's DC voltage coming out of the output. Most like a problem with the 10uF cap at the end. Somehow you have shorted it out (so it doesn't block DC) or it's bad (unlikely).
