Standard 7-string tuning is B E A D G B E, low to high. Drop A changes only the lowest string, which makes it quick to switch in and out of. How to tune to Drop A:
- Tune the guitar to standard 7-string tuning.
- Lower the 7th string until it matches an A on your tuner. It should sound an octave below the open 5th string.
- Check the 7th string fretted at the 7th fret against the open 6th string. They should match.
- Retune the other strings, since lowering one string slightly changes the others.
Drop G is the same idea a whole step lower again: lower every string by a whole step, then drop the 7th one more whole step. Tuning down that far makes strings feel looser, so heavier gauges help.
Choosing strings:
- Drop A: our S71060 Custom Light (.010–.060) or S79564 Extended Range (.0095–.064) in Power Wound Nickel give the low string extra weight.
- Even feel across the set: SU107 Extended Range in Universals Balanced Tension.
After a big change in tuning or gauge, check relief and intonation, especially on the 7th string.
