This is the guitar that I have recently replaced the tuning machines with Gotoh 510s. You may recall I ran into trouble when the last of the six Gotoh screws broke when I was attempting to screw it in. I previously reported that the repair and installation of the Gotoh tuning head has been successfully completed. ... but now unfortunately I have a new problem...
In addition to installing the Gotohs. I added a striped ebony TRC to match my pick guard and died bone bridge pins from Bob Colosi ( my third set - the K26 and GS mini already have them) . I strung the guitar up with new Elixir PB Mediums which is what they had on them before.
The problem ... the guitar sounds terrible... not at all what the big,bold, bassy, Grand Orchestra sounded like before ...

So its either the pins or the strings... cant be anything else , right?
I would not think that the bone pins would have that noticeable impact. ..effectively turning my GO into the largest Ukelele ever made.. OK that's a bit of an exaggeration, but it is very light and tinny sounding
So, my plan is to first change back to the factory bridge pins. Can I do that by loosening the strings only partially or do I have to take them all the way off.?I think I heard of someone here doing that- keeping the strings attached at the tuner, loosening them as much as needed, swapping out the pin and tightening the string back up .
Could it possibly a bad set of strings? Maybe they weren't actually mediums.
Any words of wisdom out there?
Thanks
