Brief tonal comparison between 2 Yamaha Dynamic Guitar, No.80 and No.20. I think the tone difference may be due to different string, have yet to compare with same string type:
No.80 on D'Addario XS Extra Light; No.20 on D'Addario EXP Custom Light; all tuned down to Eb.
Both installed with Graphtech Tusq as saddle.
Recorded with Rode NT-USB, Sony A6000 - Schneider-Kreuznach Curtagon 28mm/f4.
