How to Tune to FFFFFF (All F)
FFFFFF tunes all six strings to F across octaves for a single droning unison chord, similar in spirit to all-E tuning but a semitone higher. It reduces the guitar to pure octaves and unisons, ideal for drone pieces and unusual textural writing.
Start in standard tuning (E-A-D-G-B-E) and change 6 of 6 strings:
| String | Standard | Target | What to do |
|---|---|---|---|
| String 6 | E2 | F2 | Tune up a half step |
| String 5 | A2 | F2 | Tune down 4 semitones |
| String 4 | D3 | F3 | Tune up 3 semitones |
| String 3 | G3 | F3 | Tune down a whole step |
| String 2 | B3 | F4 | Tune up 6 semitones |
| String 1 | E4 | F4 | Tune up a half step |
String Tension & Setup Tips
Recommended Gauge:Reaching F on every string pulls several strings above standard pitch; tune up slowly and consider a custom gauge set to prevent breakage on the higher octaves.

Frequently Asked Questions
How do I tune to FFFFFF?
From standard tuning (EADGBE), retune each string low to high: 6th E→F, 5th A→F, 4th D→F, 3rd G→F, 2nd B→F, 1st E→F. Match each string to its exact Hz using the interactive tuner above.
Why tune all strings to F?
It creates a pure droning unison so any single fretted note becomes a full chord across the neck. It is used for experimental, drone-based writing rather than conventional chord playing.
