It's kinda immaterial whether you remove the thumbwheels or not; the mission is to unscrew the posts themselves with an allen wrench, turning them counterclockwise till they come out of the top of the guitar.But I think this will mostly be a sight-seeing excursion, as it will be clear there's no easy way to reposition the base - nor would there be a reason to until and unless you install a bridge requiring a different base angle. Both your stock Adjustamatic and the 54-2 series Tru-Arc will intonate properly on the base at its current angle. A straight bridge (Standard rocking bar, Space Control) will NOT. If you want to let the base float completely - not "pin it" - then you're free to use any bridge, and can position the base as necessary for best intonation. But if you back the 5420's posts out far enough to allow the base to float, they're going to stick up uncomfortably high around the bridge and poke you in the hand.So if you're going to unpin, it's best to just put on a standard pro-line floating base with posts that DON'T thread all the way into the top of the guitar. (Which you could then RE-pin, etc etc, but likely not in the holes already poked through the top of the guitar at the factory.) It could get convoluted. Brass, being a bright yellow metal, best matches gold hardware; stainless, aluminum, or titanium are a great match for the chrome-hardware models. Copper also looks great with gold hardware, though of course it's redder in hue.I mention color because some guys insist their hardware all match. I've let that consideration go for my own use, and go for the material that sounds and responds "best" (to my ear) on a particular guitar. Gretsch mixes hardware color on some factory guitars, and none of us object to mixed gold and silver jewelry on a beautiful girl...I really really like aluminum with blacktops; it accentuates a unique throaty twangy funky tone. It "zings." Stainless is best for a neutral tone, with maximum sustain. I like brass with many Gretsch pickups - and it works fine with the blacktops, sounding much like the factory bridge - but it's not my favorite with them.Anyway, should you choose a Tru-Arc and not be happy with the tone, you can return it at full credit (less shipping) toward exchange for another species - or your money back if you never get happy.Here's my 5420 with aluminum bridge.
