Greetings,

My OTS (built from a kit) has developed a raspy tone.  If I pluck a guitar string lightly, I get little or no sound and it is fizzy sounding.  If I pluck it harder it sounds raspy - as if the sound is cutting out. 

The mid-boost switch doesn't seem to do anything and I tried resoldering the connections with no effect but this is more than likely an unrelated problem. 

I have access to an ocilliscope through a friend but do not own one.

Any idears on where to start troubleshooting?  Any expected voltages or other testing info would be greatly appreciated.

Thanks!
