My #1 bass is the one I feel as irreplaceable. It's a mid-90s plain old black MIJ JBass, but it has the 20 years of Mojo, plus having lived through a defret and refret. The work on the neck has made the fingerboard about 2mm thinner, the radius has gone to 12", and the frets are vintage sized. These three factors combine for one of the most comfortable if not the most comfortable neck profile I've ever played. It just feels like... home. I guess I could try to replace it through warmoth for the vintage wire (AFAIK they don't do custom radius bass necks so it would be 10"), but... I don't know.
