Hahahaha I think that depends on how much of a chain smoker the seller was. I bought a Fulldrive 2 years back, when I was a smoker, that fucking REEKED like stale cigs. I didn’t smoke in my car or my house and the second I ripped the tape on the box open in my car I could smell it. Wiping the thing down there was yellow nicotine stains all over the rag like the dude just blew smoke at the damn thing every time he hauled off a cig.
And guitar cases, goddamn those things can take on an odor. I’m always nervous when i open the case of a used guitar, I never know if it’s going to smell like cigs, cat piss or both. I never plan on selling my own guitars, but I toss a couple sticks of nagchampa in my cases because the scent relaxes me. I miss the smell of 90’s Ibanez hardshell cases, though.
