Hi! I am completly lost. I bought a Four String Vantage Bass from my friend for $20. The electronics were shot so I replaced the pickups with Seymore Duncan Quarter Pounders. Other than that. The guitar is all original. I would like to do some more repair work to it, just to make it comfortable and customed for me, but I don't want jump in before I know what I am messing up. Basically, I have been trying to find out what this thing is worth, but to no avail. It is like it is the only one in the world or something. If anyone can help I would be very grateful. Thanks!
