Just had a new bridge put on my plywood and the two high strings are much higher tension than the two low strings. (I'm using Spirocore Lights and I added a medium E today that only helped a little) My luiter just made the bridge and its a quality job. The hight at the nut is as low as it could go and I just had him mess with the sound post but the D and G strings feel like spiro mediums on my carved bass. the A is floppy. Any thoughts? Could this be a case where I should just put a medium tension EA with a light D G or is there something else I can do?
