Heavy Gauge Strings Upgrade ("Core-F")

Heavy Gauge Strings Upgrade
jazz guitar core. 
For those of you who play heavy gauge strings, we designed a core that can accommodate the high tension of heavy gauge strings in order to keep the low action, which will bring comfort to playing and minimize the relief curve to the desired low neck relief. Dream for jazz players or anyone who wishes to put heavy gauge strings. 
** The jazz guitar core can reach 2.2 kg +/-
