Ben plays a couple of really, really nice banjos. They are quite expensive and sound a lot better than less expensive banjo models. They're loud with a bright sharp attack. Less expensive models are often lacking in these areas.
But you may need to adjust the head on your banjo to make it sound better. The head needs to be pretty tight on a banjo to make it sound 'banjoey'.
Here is something I heard about for making head adjustments. If you lay a ruler across the top of the head (so you need a short 10 inch ruler) you will see the that the head is depressed around the the bridge. When you tighten the head, the depression gets larger. When you can fit a quarter (lying flat, of course) into this depression, your head should be at optimal tightness.
Remember that you have to tighten all the head adjustment screws the same amount around the head.
Also, bridge placement is really important. If the bridge is in the wrong place, you will be in tune at the nut but will gradually go out of tune up the neck.
If you have a tuner, then tune the top string D (the long light string). Now play the string at the 12th fret. It should still be in tune according to the tuner. If it is flat, slide the bridge forward toward the peghead end of the neck (remember the mnemonic: flat forward). if it is sharp, move it in the other direction.
Repeat this with the wound D string.
