Some of y'all need to understand the unimportance of tunings and keys! And why:

Yes, extremely low tunings like B or A noticeably affect the tone and how it's perceived by the listener, often making the sound darker, looser, or heavier. But for smaller changes, like E standard to D standard, the difference is subtle and often indistinguishable without direct comparison or context. The way you play, your picking dynamics, and your amp settings have a much greater impact on your tone than tuning down a whole step.
