B I N G O !!! My DR and my Tweed deluxe are set to the highest clean setting , Just before breakup and THEN pushed with a Blues driver or 808 ,it creates a well defined ,ariculate,singing tone, and achieves a higher volume if desired than turning the amp higher .....to have them already pushed and THEN add overdrive creates a not only horrible tone ...but one that gets totally lost in the mix.....
