Hi Everyone,
I have a crack on the back of the headstock on my 8-yr-old Höhner B-Bass IV. It starts from the tiny screw of the E-string key.
I noticed it a week or two ago. I do not know how it started.

I do not remember hitting it against anything. I've been handling it with care. Keep it in a padded bag all the time, etc.
This is my first bass so I have no idea what to do. I bought it off a friend 2 months ago. It's a very touchy issue as I have already paid for it and most probability it was not visible when I got it.
I'd like to know if I am to despair or just look at it as a defect in look. I bought this so that I can sell it later maybe but probably it is no longer sellable. Have any of you had any experiences like this? If it use will not be affected then I can live with it and keep it till the end.
Please comment. I'm eager to hear your opinions.
Thanks a lot in advance.
Take care,
Zoltán
