With most guitars, this mode stays clean until around 8 where it begins to overdrive. Use the R1 MASTER to control loudness if you want slight overdrive at low volumes. This mode was very carefully designed to provide great rhythm sounds, from the best of vintage, Fender-type (clean or solo) to a more m

At low to medium playing volumes, the LEAD BRIGHT adds desirable sizzle, and gain in the highs to the overdrive sound and contributes to a “big easy feeling” as well. At high volumes the LEAD BRIGHT can cause real problems, such as excess squealing and noise. At high volumes it is often not necessary
