What incentive do they have to fix whatever QC issues they have? The guitar business is already massively profitable. Why would they spend more money in that area? Priority area #1 is the brand, which has been tarnished by their failed investments, and from the incorrect belief that "flawed guitars" were the reason for their troubles. Spend whatever money they need to in order to convince players that "they're back", even if they don't do anything different.
