So i have a 2018 diezel vh4. I was always obsessed with trying to get adam jones tone the amp already sounded great i just kept fiending to getter closer and closer. Time went on and i replaced the tubes to 6l6gcmstr power tubes the same ones he uses. It once again sounded great but i still wanted to get closer to the blueface tone so i searched and searched for a long time to find out what all has been changed in the circuit over the years looking though forums and what not also asking peter what could be done. From what i had found and what peter told me and confirmed was there is a resistor in the preamp and if i change that out to a 47k it will sound alot darker. There was also a difference in the feedback circuit that changed the low end in the power amp he told me if it was changed to a 22k crossed by a 100pf cap that would make it like a blueface. These two things were the big update done in 2007. Everthing else that was changed over the years were very small mostly unnoticeable differences mainly in circuitry not necessarily tone. So i made the two changes and the amp tone wise sounds fantastic and alot closer to what i like. The amp really should be exactly how is was right before the update in 07. So its sounds good and when recording it sounds good the only predicament is when im using adams settings and im sitting in front of it i get this really ear piercing treble that come through that isn’t pleasant on the ears. Im not sure if thats just a characteristic of the older style amps or what. Im just curious if other people have had this issue with the older amps or is it just me?
