I saw a video posted up yesterday with a shootout of various capacitors. Those things annoy me anyway because nobody bothers to actually read the capacitance of the individual unit, just the reported value. They then play guitar six different ways for six different capacitors and then some deaf guitard goes "see folks, if you can't hear the difference in capacitor types then you just aren't as blessed with as good a pair of ears".
This latest shootout video was posted by Stew Mac, who sell a range of capacitors at different price points. How impartial are they honestly going to be? Ditto the guys on the Les Paul forums that sing the praises of obsolete paper and oil capacitors, claiming they have more warmth/sparkle/roar and who just happen to sell aftermarket wiring
harnesses looms on the side. Some sod running a company out of their garage called "Blues Tone Vintage Luthiery ltd" or something naff like that.
Arguing with these sorts of folk is basically akin to playing chess with a pigeon. You easily win the game, but the pigeon will still knock over all the pieces, strut about and shit all over the board as though it won any way.
