My bass shows signs of having an extension on it in its past and so I'm not too worried about the cosmetics part. I'm more interested in the practicality of having one installed. My goal is to join a community orchestra and my instructor and a local luthier have commented that my current bass is good enough for that level of performance. And frankly, I'm getting quite used to it, so I'm wondering if I should consider one sometime during my development so that I get used to using one well before I get to the orchestral level or are they really not that big of a deal to have?
