For christmas my family and I went to Paris. On our last day there, I had the joy of playing a little contrabass (double bass). The store manager said it was an old model, and the sound was wicked. It was incredibly deep, and dark, and evil, in other words perfect. Today I tried a fretless, hoping to get a similar sound, but alas I was greatly disappointed when I found that it had almost the same sound as the fretted back home. So my question is as follows: Do you know of any fretless basses which sound very close to a double bass? Very international dealers only, please.
