Not sure what you’ve replaced at this point but tap tone and resonant frequency is huge and is different in all woods no matter the species. Tap the body to see if it sounds dead and thuddy. A ping would be the goal. Short of replacing the body, threaded steel saddles in a .06”-.065” thick steel ashtray bridge baseplate. Top loading the strings will decouple the body from the bridge and be much brighter. Check out Jim Campilongo as his teles are set up like this. Ernie Ball slinkies are brighter strings IME as are stainless. You want as much steel in the strings for greater magnetism. 9’s would be brighter than 10’s but I like 10’s. The Gotoh baseplate was brass so steel is much brighter and the direction you want to go. My summation is wood resonance is everything! Next, using steel hardware (baseplate and saddles) and high steel content strings and only use brass to tweak the eq desired. Decouple the bridge from the body by top loading the strings for more string energy from the bridge. Lastly, low output pickups should be fine for more highs and twang. Good luck!
