Hi All,   Not sure what to do, but everything sounds muffled to me on the Helix LT. Factory Presets, purchased presets (fremen), from scratch presets, etc.   I am playing a Paul Reed Smith DGT and a Fender Standard Strat primarily, but have tested 5 or so other guitars of different sorts (hollowbody, mini humbuckers, noiseless vintage single coils, etc.) Speaker wise, I am using primarily a PowerCab, but have also played through an Alto 310, JBL LSR305 Studio Monitors, 4CM wi
