Thinking about a Sadowsky, I'm a JJ fan, and need a good slap sound. recently I read here someone had a PJ bass with a J routing option under the pickguard. That makes me very curious. I've never owned a PJ bass so my question is:how does the sound differ? Is the low end more round? Deeper? more mids? Also, being a fan of the string spacing of my MTD I need to be assured that Sadowsky has the same specs more or less. Any MTD/Sadowsky owners out there? I assume the fretboard radius is fairly flat on Rodgers basses as well, is that true? Thanks.
