I bet it is a whole lot easier to hear a difference in the room. I hear the direct sound of the strings of the guitar being close to the same volume as the amp. It would be nice to hear that there is a difference in changing tone caps only because I have heard so many talk about it. What is the worst sounding tone cap and the best?
this short video was made for the guitars owner...she heard the difference immediately ... there will be a full video soon showing what was done.... :)
