The Fralin Magic Cap is a .0015 Capacitor of Sprague Orange Drop that Lindy swears by. When activated, your plain strings will sound thicker and larger – immediately. This Cap is perfect for anyone looking to add a bit more functionality to their guitar, but doesn’t need a ton of highs rolled off.
The “Magic Cap” is simple: It rolls off just the “shrill” tone that comes with a Bridge Pickup of your Strat or Tele. It’s perfect for those who want to thicken up or darken their tone just a tad when playing solo notes, or chords. The Magic Cap won’t make a drastic difference in tone, rather, add more functionality to a common problem with guitars.
I like the .0015 and call it a magic cap because it makes a Fender sound a little more like a Gibson.
