This a a really nice H54 Rocket. When I purchased it it received a new rock maple fret board and Evo frets along with a new bone nut and a tune-o-matic style bridge. Also the pots for the tone were replaced with brass shaft CTS pots. It seems that Harmony used cheaper aluminum shaft pots on the tone controls and the brass shaft pots for the volume controls. I also replaced the tuners with new Grover vintage tuners.  It plays and sounds great. I like this guitar a lot, but the old joints in the hands are really getting bad and I decided it was time to let someone else play it. I think it deserves to played.  It has been played sparingly at my house. It shows the usual small dings and aging cracks in the finish, I will also be putting some other guitars from my vintage collection up for sale. So check them out.
