Hi. I'm new to double bass and have just bought a 20 odd year old Boosey & Hawkes 1/2 size bass. The dimensions of the bass are more like 5/8, and the string length is 38 1/2 inches. I am 5'11 so the end pin is fully extended. I have heard that the string length can be increased by moving the bridge down say an inch, then adjusting the tailpiece and sound post. I intend to study and play this instrument, and when I can afford, to upgrade to 3/4, of better quality; I am worried about learning all my scales, shifts etc and developing poor technique due to the short scale e.g., I'm using my third finger a lot if playing in Ab or Db in first position, because I can. I'm just concerned the shorter scale will allow me to become stuck with bad habits, therefor that is why I was thinking of modifying the string length. Any suggestion; has anyone modified a bass this way?
