Ok my previous test may have been flawed. Because the G&L has more sustained "tone" than the Jazz or Ray I had them turned up quite a bit louder which of course made them seem "bassier".
With everything level the bass response of all 3 seems about the same. Furthermore the Ray and Jazz could have been recorded thru my Sebatron Valve preamp which would emphasise bass. I've been using my Great River Me-1nv for the Asat. I'm really a guitarist and have no bass amp.
Here's a small di clip thru the Great river. First pick then fingers.
If there's something wrong with the bass I'm not sure I would repair it, because I really like the sound of it.
