The sounds are different. The buckling springs are lower and more rumbling, and the blue Cherries are higher and more penetrating.
Dental floss in buckling springs and landing pads under Cherries will both attenuate the sound quite a bit, especially in the registers that tend to annoy your neighbors.
I think I may go ahead and do that mod later on, also on another note. What is the best cleaning method for cleaning out these keyboards in your opinion? Is there maybe a chemical you can buy in store to get rid of deep old marks in the board/keys?
I pull all the keys first thing and give them a bath in a liter of hot water with a spoonful of powdered laundry detergent and Oxi-clean.
If I can take the whole thing apart, I go to the kitchen sink and scrub everything but the electronics in hot soapy water.
Without taking it down to pieces, vacuum it out good and wipe everything down with rubbing alcohol. Use Q-tips in tight spaces.
Adhesive residue needs an organic solvent like citrus oil or naptha, but, remember, these same solvents can be hell on plastic.
Black marks that are not actual scratches can sometimes be removed with a pencil eraser (white is more gentle than pink). Those big soft spongy eraser pads (Mr Clean?) are good too, but will quickly make a shiny spot if you are not careful.
Something really traumatic that makes you start thinking about sandpaper - consider scraping with the edge of a sharp knife blade.
