First, if I misspelled anything or didnt get the model number correct, forgive me. Its feels like its 159 degrees here in Mississippi and ive been out in all day, so I'm doin good to even spell my name! Anyway, a friend, a very good friend, bought me a new Gretsch Jr. Jet bass or whatever its called. Wow! For 299, i think its a steal. For a gift, well u cant get much better. Actually I'm thinking about making this bass better. First, I was gonna put some Hipshot or Grover ultralight tuners on it. Does anybody know of a direct replacement? Second, new pots and maybe getting rid of the pickup selector switch and adding a blend or another volume. Ive read if u were gonna use CTS pots, then u gotta bore into the body? Is that true? Also which do I use? 500k? 250k? Ive not even opened it up. Tone cap recommendations? Then we get to the pickups. I like these but if there is another one that sounds better, please let me know. Thanks!
