What I don`t like about the Jazz bass is this it seems with the neck pup soloed tone is fat and big, sometimes the bridge pup soled is a little thin. With the volume at max if you change from neck to bridge pup it seems it lowers the output volume. Do you notice this or I am a bit crazy??? I am having the roscoe beck of a friend I am planning to buy it. It is the only thing I don`t like of the bass. It is a great bass overall, better than my sr5, however that thing of the pups I don`t like. I have asked a luthier and he told me that was normal in every jazz bass. The RV5 has a switch to change the pickups, it seems when I change from neck to bridge the output volume lowers a bit.
