I have several basses at my home currently, an old bass and a very new bass. The old bass, I was told, is 200+ years old. It was restored by this place and it has no tag, but it is very responsive to the bow. It, however, has an extremely tight sound in the upper register and the fingerboard only goes up to a B. It is a round back. It is priced at $15,000. The tight sound could possibly be from set up, but it would take some experimentation to figure this out. The new bass is two years old, although it really has only been played for a year because the girl who owned it stopped playing bass and has had it laying around. It has a louder overall sound, but the bow response is not quite as quick on the sixteenth notes. It is in excellent condition, unlike all of the cracks from the restoration of the old one. The fingerboard goes up to a D. It is a flatback. My teacher has also suggested that the strings on the bass could be replaced to get a better sound. This one is a Lakeburg and Baer and is priced at $14,300. I am a high school junior who is planning to pursue a career in music. I currently have a plywood, but I'm looking to take the next step up. Both instruments are very nice. My problem is the bow response issue. Although it's likely, it's uncertain that if I bought the newer bass that the sound would get fuller and better bow response. I have pics that I'm trying to get on the site. What would you guys recommend?
