Hi Joseph....I do not own the GH1 but I do own an old semi-vintage RS1 and the mahogany has darkened over time and it looks wonderful.
I know maple will darken over time also and it looks like the sweet taste of honey, very nice...probably will just take more time for it to darken....probably will happen and you may not even notice it for awhile
I just bought a can made from ormosia wood and I cant wait to someday see its transformation.
Here is the darker mahogany RS1
Also a big congrats is in order for you and your new BHSE...I saw the pics...absolutely beautiful, sir
