Now I have owned two nine string basses for a couple of years, I play it exclusively and I play it a lot! In my area of the country there is not a lot of selection at the retailers so I have used in the past what is made available by the companies who focus on marketing rather than high quality strings... Getting into the 9 string basses forced me to seek out strings that work for the instrument... This last week I strung my fretted 9 with a customized batch of singles from SIT... I let the bass sit for a few days before adjusting the truss rod... now for the miracle... I had to do two + turns with my truss rod wrench... The point, these things are much tighter tension string than other brands I have used on the 9... Many bass builders who are trying to solve problems by building 35" basses, etc., maybe the answer is not in scale length ... it could be in your strings! I suggest doing an experiment! For those of you seeking a "TIGHT low B" you should just try SIT strings. The tension on these things is NUTS! And depending on whether you like steel, nickel, dead, bright, flats, rounds ... whatever... They can meet the needs from what I can tell... Man, if you only knew! I am not a SIT endorsee nor an employee... In fact to add validity to this thread I'll tell you that i am a Dean Markley artist... probably not for long due to this thread I just wanted to share this experience because I think that people don't consider the variables very often ... you might be looking for a tighter B and trade your beloved bass because of it, when possibly trying a different brand or style strings may be the answer! No matter who the mfg. Is... String tension seems to be a mysteriously overlooked variable in the world of great basses!
