Spending a few years with trial and error, Ibanez finally reached to out-of-the-box X-M Bracing to generate the ultimate sound standing out on the stage. The carefully designed scalloped X-bracing, the allocation of tone braces and finger braces transmit the string vibration efficiently through the bridge to the body. The X-M Bracing creates the clear bottom and crispy treble sound with trimmed warm mid-range, yet providing wide dynamic range and highly response.
