Does anyone here know much about Gibson J45s? I'm more of a Martin guy, but I just inherited this guitar. It was my grandmother's. She was given this guitar in the early 60s. I think it's unusual because it's all black, and I've never seen one all black. It also has a tag on the headstock that says "Custom." I assume that has something to do with the color. 
I've played this thing every day this week, and I've noticed that it doesn't have the sound my Martins have. It has great low end, but overall, it seems to lack sustain and even sounds a little boxy and dead. 
Again, I'm not that familiar with Gibsons. Maybe that's the way these sound. 
Another thing I've noticed is that there are two large screws on the bridge, I assume used for raising and lowering the action. I tend to play with my hand resting on the tailpiece, and when I'm strumming, that top screw chews the heck out of the palm of my hand...right there in the fleshy part near the wrist. I'm wondering if there's any way to update the tail piece with something that doesn't have those screws. 
The serial number is 108506. 
Any comments, help, or thoughts? 
I'd insert a picture if I knew how. 
Thanks
