If you’re looking for a guitar tone that has a thin, bright sound, single coil might be the way to go. These pickups are used often for clean tones. However, if you’re playing a genre of music that requires lots of tonal output and distortion, dual-coil pickups are your best bet. Pickups determine what is sent into your pedals, amp, and cab, so the ones you choose are going to have a strong affect on your overall tone.
The tone on these loop chords is so low and pillowy, I don’t really know what to call them. I think I’m hearing them as D♭ and Cm. I’m sure the key we’re in is A♭ major because of the melody, but that means it’s a IV and a iii chord — there’s no tonic chord to establish the key, in keeping with the modern anti-establishment trends we’ve been tracking.
