Chandler Bass - remove-able neck.

[Eric Hochberg]

I have no experience with Chandler basses, but you need to take it to an experienced bass luthier to discuss the sinking top issue. The other problems are relatively minor. Get a price to repair the top properly assuming it is repairable. How much is the bass worth to you in good shape? That's the main question to be asking. You don't say what you can buy it for as is. Add the cost of repairs to the purchase price, and there you have it.
