LOL To be fair, there is a guitar player off center and back stage, which is still an anomaly. The lengths this company goes to keep people smelling like my grandpa...
The only thing bass/scent-related for me is my Fodera Emperor Standard 6. For some reason, the case is scented like vanilla whenever you open it. My Gibson Flying V guitar also has a vanilla scented case.
Not a bass, but I always say that when I bought my baritone saxophone the only thing holding the case together was 40 years of congealed beer vapors and nicotine deposits. When you opened the case it definitely added something to the ambience.
The odor from waterproof backpack approaches genuine FuNkY. I roll it open away from my face. Don’t think Old Spice is going to fix that.
