I absolutely love the clean sound of my les paul studio through the vibrato channel in my DRRI. With OD pedals, it gets some of that "buzzing" that everyone seems to talk about due to the bright cap. It sounds OKAY at louder volumes, but is pretty bad at bedroom levels. Im exploring options before going with the bright cap mod. Ive heard a little about speaker changes doing the trick. Does this void the warranty like cutting the bright cap does? I just sent my TS9 in for the silver mod, and Im hoping that by itself will make it sound a little better. Thanks for any help.
