A friend of mine had me look at an old Yamaha RBX-250, single P-pickup bass. This thing was laying in his shed for over 3 years collecting dust (and a lot of other ??? debris). We live in the Pilbara which is a very HOT place in Western Australia where a typical summer day is around 110-115 degrees fahrenheight (42-45 C) with humidity consistantly around 60-65%. First thing I noticed on this bass was that the neck was straight and the rosewood fretboard (albeit dry and debris covered) was not cracked and all the frets appeared to be true and seated well. This thing was beat bad, too...a definite victim of a rageful teen punk rocker or a VERY frustrated musician. It had a huge chunk taken out of the finish and there were dings all along it. Whoever tried to string it, did a bad job as the E-string didn't even break over the nut, hence it was flopping about when you tried to play it. So I took everything apart...even soaked some of the rusty bridge parts in CLR. I cleaned it lovingly. I used a toothbrush and windex to clean the fretboard and then hit it with a nylon scouring pad. Then I oiled it with machine oil and rubbed it through and buffed it. It came up BEAUTIFUL. I then restrung everything (properly this time) after cleaning the strings with windex (a quick soaking and wiping). I plugged it in and the pots were a bit scratchy (I suggested replacing the pots to the owner as you can get a p-bass wiring kit quite reasonably). But when I set the pots, and plugged it in...SWEET, SWEET, SWEET....what a nice tone. Vintage p-pass with a nice controllable growl. WOW! I then tweaked the action. I didn't set it too low, as I didn't want to take away from the fact that the owner is a non-bassist and he has big thick fingers that would initially have a heavier touch. I set it to where it was playable and just a tad too high for me. And boy can this puppy sing! I was amazed! A cheapo bass that's been really badly abused, with half-dead strings, and scratchy pots...and it has such a sweet voice. Unreal!
