Hi,I am looking for some advise on bridge work.Before I start let me just say I'd prefer to have the luthier I've been using do this work,but I heard thru the grapevine that he's in rough times and he's out of his wifes house where the shop was. My bass is a '57 Kay MIB,with aluminium adjusters.I have the adjusters as low as I can,but the action is still too high.( I play old country,realllly freaking loud ,as well as slap style rockabilly,bluegrass,and standard jazz,rock,polka.You get the idea.I need a very versatile bass.) So I want to sand off some of the top of the feet of my adjustable bridge.(Does that make sense?) I've done quite a bit of my own work on this bass before,and right now I have the bridge off,and the sound post hasn't fallen yet! Any advice on how to proceed? Thanks!
