is the guitarist blasting 24 hours a day? does he come home with you and blast while you're trying to practice on your own?
come on, dude, you know what i meant...once you learn how to tune by ear, then you can use a tuner for times like when your guitar player blasts.
Ahaha it sure feels like it! I know if he could he'd follow me around all day soloing. (Yeah, that kind of guitarist... Writing a song "so uhhh, where should I solo?")
As for tuning by ear, I can't pick up a horribly out of tune bass, pluck a string and be able to get it back to E or A or whatever with no reference, but when I'm playing I can make adjustments to my tuning on the fly if a string starts sounding a bit flat.
