   Hi Patrick,   
      
   why not measure the values of the aged components of the tonestack and   
   "clone it"?   
      
   The older good Fender pots usually don't change R values much.   
      
   I plotted the response carefully though.     
      
   second  - the big variable in "Sound" is the speaker. It changes more   
   than a little bit. Especially with the DRRI.   
      
   Well yes, but Its worth a shot to re-engineer the tone controls.   
   I have heard fabulous music from modern speakers, even though they have a bad   
   reputation with many musos who I sometimes think have irrational fondness to   
   items from the "good old days". Not all their opinions are wrong though, and   
   this time the amp    
   owner was dead right about what he hears. OK, let me try something rather than   
   blindly copying, and if the guy is happy, then mission accomplished and I am   
   the wiser for it.   
        
      
   AFAIK the TSC is the only readily available software. And it only does   
   the tonestack. It does not cover the "bright switch" - or cap, nor the   
   cap across the isolation resistor of the reverb and so on...   
      
   Yes, seems like TSC is all there is, and was made up by a Mr Woodgate who   
   seems non-contactable. I may be FORCED to learn how to simulate with R&C and a   
   decent simulation program that accurately predicts response of any R&C network   
   one is likely to    
   compose.   
      
   Ampeg have a Baxandal type of tone control, no cheapy silly "stacks".    
      
   I'll have another look at Ampeg circuits. ,have    
      
   regards Jochen
