PRS tremelo problems

Hi all,

I’m a new member and thought I might get some feedback on my PRS SE problem. I bought my first electric recently, a lightly used PRS SE Paul Allender, and found problems with the tremelo bridge. With all the strings in tune, the bridge front edge was resting on the guitar top and the back edge was about 3mm above the top. Also the front edge of the bridge was out of parallel to the pups by slightly more than 1mm. I removed the bridge and found the knife edge holes and mounting screw undercuts were damaged. I decided to buy a NOS MannMade Bridge and, when trying to mount it, found the screws would bind at different places in the bridge holes. I stopped trying to mount it and measured the bridge holes and guitar top mounting holes.

The MannMade bridge holes were perfectly spaced and in a straight line.

Measuring the machined mounting holes, in the guitar top, showed they were unevenly spaced over .01 but more significantly weren't in a straight line. I put screws in the first and last holes in the top and placed a precision straight edge against those screws and found, the 4 holes in-between were not in a straight line with, some out of line over 1mm.

Bottom line is that not only were the holes poorly located, but were also shifted as a group, about 1.5mm towards the base side. This caused the strings and pole pieces to be mis-aligned and the high E string was near the neck edge at the 24th fret and the low E was inboard of the edge.

The mis-alignment was the same with the original bridge.

It is also probably the reason the original bridge had damaged holes and screws and was poorly setup.

Has anyone experienced a similar problem?

I have a small machine shop and plan to put the guitar on one of my milling machines to correct the hole location. Any thoughts on other repair methods will be greatly appreciated.

Thanks,
henryr
 
Re: PRS tremelo problems

get a hipshot tremolo, drill 2 holes for the bushings for the studs and have a far superior tremolo system.
 
Re: PRS tremelo problems

Thanks for the replies. Vasshu are you suggesting to redrill the six holes. Drilling and plugging is what I had planned. Does anyone else think the hipshot trem would be noticeably better the the NOS Mannmade trem?

Thanks,

Re: PRS tremelo problems

I don't. John Mann trems are awesome!! Once you get it installed, you will be more than happy!
 
Re: PRS tremelo problems

Aleclee thanks for your reply. I'm guessing "this" " means you agree with Vasshu's suggestion. Is that correct?

Thanks,

Re: PRS tremelo problems

Examine the six vibrato screws. American versions have a notch machined in them to meet the knife edges in the bridge baseplate. To obtain proper contact, the six notches have to be aligned very precisely.

I have never worked on a PRS SE vibrato. I do not know whether these also have the precision engineered notch and knife edge arrangement.
 
Re: PRS tremelo problems

The NOS Mannmade bridge, made by John Mann, has the notches as do all the PRS american made and Korean made trems.

Thanks for all the replies. I thought I already posted the following but can't find it so here it is again.?
I setup the guitar on a milling machine and milled new, properly located .1875 I.D., holes. I turned a mahogany rod into .1875 diameter dowels on a lathe and in the same setup, to maintain concentricity, milled holes in each dowel per Mannmade dimensional instructions. I filed glue grooves in the O.D. of the .1875 O.D. dowels, coated the dowels and I.D.s of the .1875 holes with titebond, then pressed the dowels into the new holes in the guitar top. I made a #6 wood screw tap to create the mounting screw threads, to avoid potentially snapping off the brass screw heads. The Mannmade bridge mounted perfectly and the strings are over the center of the pole pieces. All is great.

Best Regards,
henryr
 
Re: PRS tremelo problems

Contact PRS.

I'm not kidding.

They take the Quality Assurance of their SE line every bit as seriously as they do their USA-manufactured products. This kind of thing is very rare with PRS guitars, even the SEs, which (to me) are typically at the very top of the pile when it comes to quality of non-Japanese Asian imports.

Give their customer support a call and see if they can do something about it. I know your guitar is used, but they may still help.
 
Re: PRS tremelo problems

Hi,
I had several email discussions with PRS and said they stand by their products and asked for pics of the problem. I sent them about 6 close ups and they agreed the holes, made in Korea, looked mis-located and was probably a Q.A. issue. They initially offered to have me ship them the guitar and if they agreed it was a manufacturing hack, they would give me a new PRS SE Custom 24. I had already bought all the endmills needed for the job and have a small machine shop so I decided to avoid having wasted money on cutting tools and paying shipping costs and do it myself. They did give me a gig bag for free for my troubles.
