How to Tune to AAC#EG#E (Bug Collector)
This striking open-A-flavoured tuning (A-A-C#-E-G#-E) features a very low A on the 6th string an octave below the 5th, like a 12-string octave pair split across the two lowest strings. Haley Heynderickx uses it on 'The Bug Collector' for its haunting, resonant open sound.
Start in standard tuning (E-A-D-G-B-E) and change 4 of 6 strings:
| String | Standard | Target | What to do |
|---|---|---|---|
| String 6 | E2 | A1 | Tune down 7 semitones |
| String 5 | A2 | A2 | Leave as is |
| String 4 | D3 | C#3 | Tune down a half step |
| String 3 | G3 | E3 | Tune down 3 semitones |
| String 2 | B3 | G#3 | Tune down 3 semitones |
| String 1 | E4 | E4 | Leave as is |
String Tension & Setup Tips
Recommended Gauge:The low E must drop all the way to a low A (an octave below the 5th string), which needs a heavy string (~.060+) to stay clear. The B string tunes up to C# and the high E stays E; the G tunes up to G#.
