I like Traben basses better, but yes, Id say the Lacklands do low B string a little better.
The neck thru diff in my experience is ussually a little loss in midrange. Bolt ons just tend to have a little bit more of a midrange up notch to their sound to my ears. Depending on the bass or guitar this can be a minor thing or non issue. Neck thrus will also often have a bit more treble edge to them due to the extra maple in the body part of the instrument. A maple bolt on with mahogany body will be little darker sounding then same model same everything except maple neck thru body with mahogany wings. As an example. If the instrument also has a maple top, this can become too trebly a voice for some due to maple top plus addition of big maple center thru body from the neck. Lacklands neck joints are superb so comparing the lackland to the neck thru traben will prob find you hearing more treble then you want with the traben. Esp for low B. Imo
