A strat is a strat is a strat.... and it's hard to change the OVERALL tonal qualities of a guitar just by electronics... But if you're looking for more of a warm tone try changing out the pots to 500k pots. Most likely the pots in there are 250k pots, which give you a clear treble like tone that the strats are known for... If the 500k doesn't cut it... you can try 1 meg pots to further warm the tone.

Just a little trick for changing the tone of a Strat... nothign spectacular.
