Despiau Bass Bridge 3/4 Adjustable

I put this bridge on a cheap upright, to improve the sound. It did ok, the adjusters work fine, wood is nicely chosen and sound vibrations were better transmitted than before. Of course I wouldn't put a bridge like this on a better instrument, that's a nonsense.
Pros: not very expensive, adjustable, good upgrade for a cheap bass
Cons: not the top of the market of course, to upgrade a good instrument please consider spending something more or going to a luthier to find out what's best for your bass.
