Re: Where does the Fuzz come from??

Let me preface this by saying I have not read the entire thread. Having said (ha, ha) that I think some fuzz is coming from the 2nd gain stage 2.7K/.1uF combination. The problem with trying to squeeze a lot of gain out of 3 stages is that you are going to hit a point where the gain will become fuzzy and there is no way around that. You can try to raise the voltage on the power rail to try and off set the difference a bit but you will roll off some lower mids, which You may have better results backing down the gain on the 2nd stage and adding a 4th gain stage to the design to get the desired amount of gain but with less fuzzy/buzzy characteristics.  
 
There are many ways to stack up gain so try as many as you can to find what works best for you.  
 
 
Hope it helps
