I just picked up a Sadowsky Metro that is very nice but the action is not to my liking. The neck will adjust straight with ease but the upper register is my issue. I have the G string saddle bottomed out and it's close to where I want it but not quite. The only option is to shim the neck. Have any of you ever had a need to do this on your Sadowsky? It's not a big deal, really, I've done it many times but just wasn't expecting to have to on a bass such as this. In fairness to the Sadowsky, most would be perfectly happy with the action as is but I like it low. The fret work on this bass is so good that I know it can go lower with a shim and not cause any fret buzz.
