I have a Kubicki Ex-Factor with the laminate neck, and there's definitely a dead spot at the 7th "D" fret of the G string.antipodean wrote:I believe that Philip Kubicki did a lot of experimentation and believes that a less massive headstock on a full scale bass helps eliminate dead spots. He also uses an ultra-stiff multi-laminate structure for the neck on his basses.
In my experience, every bass has had some sort of dead spot where the note's frequency gets absorbed by the bass - the variable is where it's located and the extent of the "deadness". While the G string "D" seems to be the most common dead spot over a wide range of basses, I find Rickenbackers usually exhibit this issue between the 3rd and 6th fret of the G string. This will also show up on the D string between the 8th and 11th frets (since its the same frequency). Like Jeff, I had the best experience with a graphite neck bass (a Modulus), but the dead spot was still there, albeit much reduced.
