Weezer, "Say It Ain't So" guitar lesson. Next we're using the Blackout Effectors Mantra overdrive to match the fat, chugging tone in this song's chorus. You may not notice at first but the meat of the song follows the same chord progression of C#, G#,A, E, and changes the accents and shapes of the chords for a different feel. Say It Ain't So can always be recognized by the "off" open B string during the intro G# chord, a sound that always perks up the ears. During the chorus, the Mantra overdrive fits the bill with a multi-stage circuit that delivers dynamic, amp like saturation. Enjoy your daily guitar lesson.
