Re: EPFM Ring Modulator
I got it working, yeehaw.  
 
I did plan on, and still do, adding a cap switching scheme to extend my frequency range. It is a pretty decent sounding ring modulator, but I do have a problem. It is very noisy. I have a constant ringing tone even when nothing is plugged in. The null pot helps, but does not eliminate this problem. Is this circuit supposed to do this. I'm no stranger to ring modulators. No other RM I've played through has presented this problem.  
 
Thanks JMF
