The first bass I owned was a white Squier Jazz bass, if I remember correctly it was made in Japan (Got it new in '93) and wasn't all that bad actually. I put a Kahler trem on it, solely because I came across one in a guitar store and was pretty amazed that they even existed. Big mistake. Not long after that, I came across some really heavy gauge strings. bought em, put them on, tuned up, did some crazy thing with the whammy bar, broke the nut and warped the neck.
So I brought it down to a friend of a friend who did guitar/bass mods/repairs/etc, to get the neck straightened and a new nut installed. Not only did he manage to bend the neck even more, but he also managed to do such a crappy job on the nut - string spacing was totally irregular. Never heard from him again after that.
I still have the body - tossed the neck out years ago. Don't know what to do with it tho, since it has the Kahler bridge route (still have the Kahler too).
