Hello
My uncle gave me his bass guitar...He bought it about 30 years ago and now he don't use it so it's mine now

The problem is that the bass need some changes...
I need new key tuners and a new bridge.
It's not a famous brand bass....It's actually a Sound Sender Prestige Bass..
So I need help..If anyone can help me your advises is more than welcome!!!
I can post some pictures if you want!!!
Thanks
