Mark Arnquist has kindly written a technical article describing how modifications to the stock bridge of the 4000 Series can assist in the intonation of these fine basses. Please visit

Mark: This is a really ingenious modification that is certainly looks user friendly. Tell me what adjustment screws you might change at the same time compared to the stock bridge.

I some times install stainless screws or hex head screws,this depends on which ones/style the owner wants or feels 'last' longer.
I sometimes also redrill and retap the height screws to a larger diameter .This is only slight ,but can give a firmer footing.
I have also in the past ,drill out the hole entirely and made a hex post for the bridge to sit on and drill and threaded the bridge base.
I then use a pair of nuts ,locked togather ,under neath for the bridge to sit on .From the top it looks virtually stock.It no longer rocks out of place when you restring.Sort of the Gibson Tun-O-Matic idea.Call it the Rick-O-Matic.
