Hello, nobee here but I have a serious question. I bought a Juzek bass a while back which needed some work. I took it too a well known luthier close to where I live. Here is the problem. It appears that the bass sat somewhere, before I bought it, and some kind of oily substance got on the bottom part of the bass. The luthier I took it too can not get the glue (hide) to hold around the end pin block and bottom of back and front of bass. He has tried everything he knows to do to remove this substance so the glue will hold but at this point nothing seems to work. Any one who might have any suggestions on this, please let me know. Thanks.
