I want to improve the tone on my deluxe because its pretty muddy. This is an article i found about mods someone did to their tele deluxe would those mods improve the muddiness and if so where i can i get all that stuff and how hard would it be to install all of that? And if i was going to put new puts should i put 500k or 1 meg pots?

1 megs. More tonal range from a 1 meg than a 500k. But 1 megs i think work better with higher-output pickups. You should also get all the same cap values he used, as well as a new switch and a new jack. And all the stuff he put into his guitar is pretty simple if you can solder.
