sorry to be the nay-sayer here, but a 35" scale is absolutely NOT required to get a solid, thumping, and totally tight B-string. the key it an extra stiff neck and how you align the grain of your neck shaft woods. also important is your string selection (material, diameter, and how it crosses over the bridge)
as proof, I have a 33" prototype that I've load to several local pros to demo. they all have commented on it being the most comfortable playing 35" scale bass they've ever played before. when I then share with them that it's not a 35" scale or even a 34" scale but instead a weenie 33" scale, there is a look of confusion on their face as they wrestle to believe what their ears/hands have just busted a myth equally as large as the anointed instrument wood myth
