Changing out the electronics in your axe will do alot for tone.. Dont get hung up on RS stuff it is way to high and CTS pots are average at best.. Using Papper in oil caps works wounder for a sweet tone and I would try the jensen caps for it. I have not used them because I have vitamin Q astrons sangamos amoungst others.
Here is some wiring diagrams for you to look over if you want to change it to ventage specs..
It does make a difference in the sound..
I went to the mussic shop close to my house and bought some new pots for my hamer , They came in a mint green package and had WD in black letters. They seem to be working fine and they only cost $2.50 each.
My hamer had CTS in it and they were junk. The lugs were lose and shorting out on the carbon strip..

Peace man and I hope you find the tone you seek.
