When replacing potentiometers (pots), there are differences in shaft size you’ll need to be aware of. The shaft we are referring to is the part of the pot with threading that sticks through the guitar top or pickguard where it is held down by a threaded nut.

In my opinion, if you have the smaller diameter shafts, it’s worth reaming out the hole to accept a 3/8” shaft. The larger diameter pots are typically higher quality in all aspects. Fortunately, you will usually only find small diameter pots on the cheapest guitars. Always use a reamer to enlarge the holes because a twist tip drill can crack the wood of the guitar top.

We can’t resurrect or improve every beaten, tired, old pickup that we come across. Some of them, like the ones seen above, are just too far gone. Only a complete rebuild, with brand new parts could bring them back to life, but at that point, you may as well just replace it! You can’t shine a turd, as they say — and even if you could, you’d still just have a shiny turd. But, just maybe, your dull sound isn’t the turd you thought it was, so in this edition, we’ll address the possible causes and potential solutions.
