1. Replace the tone cap (most commonly a .022uf or .047uf) with a .1uf cap. Preferably a Paper-In-Oil (PIO) capacitor. This single modification will take some of the brightness out and warm up Your Tone. There is a reason Eric Johnson uses this cap value.
2. Stratocasters have a tremolo cavity on the back side. Covered with a plastic cover with 6 screws. Remove the cover…. And experience a big difference in Your Tone and Overall Sound.
3. Remove all paint from any location that is not seen. Under the bridge, inside the pickup cavity, under the pick guard. These 3 locations are easy to get too. This will allow your guitar body the breath. You will love the change in tone!
4. Replace your pots and wiring with good quality components. Cloth wiring is best.
These are simple and inexpensive mods that are easy to do and will make a difference that you will hear. Each will have a distinctive change in your guitars tone. Have some fun …. and give it a try. Enjoy your New Tone!
