Whine is oscillation. Ground problem is a good guess; slight mis-wiring is another one. 25K for 22K is fine.  
 
Try reading the DC voltages at all the pins of the transistors and opamp and reporting them back here - that's the best first step to debugging this one.  
 
You don't mention - does the guitar sound come through?
