How long does it last for you? On a really good bass it can last up to six months for me, then it starts to wane and by a year I want another fix. New crappy bass usually lasts a week or two - I won't be buying any more of them though, I hope. I've got my first double dose on hand here and I'm getting all stupid silly. I just got my first Bongo only a few months ago, I'm still high on it, and i have another coming in a couple of days... hope I don't OD. Let's talk about bass highs.
