Well comparing different values is flawed for a start as a 33nF on 6 is not gonna sound the same as a 22nF on 6.
What I hear (with headphones on) is subtle at best when a difference is even apparent at all and can be explained by tolerances.
His 22nF orange drop cap may not measure exactly 22nF, it may be 23.5nF and his ceramic may actually be 20nF,hence they will sound different on 6. One would have to measure every cap and match them exactly to the desired value to do this test so its flawed from the start.
Its all about tolerances,not type and any money spent on so called high end caps (they are all a matter of cents, not dollars) other than the cheapest 10 cent cap is a waste of money!
A 10nF cap will sound different than a 47nF cap on 6, no doubt about it but it has nothing to do with type its the value in this instance that is making the change. So,again, its tolerances and nothing more.
The kind of people that swear by certain caps are either selling them, brainwashed by mojo bull#### and what they are hearing is tolerances or they are lying, its as simple as that. And after all,if you just spent $50 on a 10 cent cap you would want to hear a difference too wouldn't you?!?!
You know what type of caps are on vintage Jaguars, strats etc,the guitars with all the "mojo"? Cheap ceramic disk caps...they cost 10 cents each.
Another bull#### story is "vintage pickups sound better", this is just crap and is illogical. So what, somewhere during our advancement in science and technology we lost the ability to make good pickups? Sure!
A vintage jaguar sounds identical to an AVRI jaguar in one comparison I heard and when there is a difference in another comparison,its other factors like wood density and the Kohms of the pickups/pots etc.
The guitar world is so full of #### its not funny! You need to sift thru this #### to get to the actual facts and save yourself embarrassment and money.
