In this series of articles and videos, I show how potentiometers work, demonstrate how the different tapers sound for guitar volume and tone, and explore in what situations you may want to replace your guitar’s pots. Enjoy!
I’ve read stories of people saying how their guitar sound miraculously better after just changing to a different brand of pots. Are they just imagining it? Let’s investigate. In my earlier post Pickup experiment – bypassing electronics, I determined that entirely bypassing the electronics on my Epiphone Riviera P93 did marginally brighten up the sound. […]
Here’s part 2 of my potentiometer project. In this one, I compare linear and audio tapers, and compare the different audio tapers of Alpha, JS, Bourns and CTS pots. Then I go over a bunch of other factors to consider when buying new pots- tolerances, dimensions, shaft types, etc.
Next up in the series on guitar pots, I demonstrate how to enlarge the holes in your semi-hollow body top, to accommodate the larger diameter 3/8” pot shafts. Import guitars appear to use slightly smaller 8mm or 5/16” shaft pots.
How do potentiometers actually work, and how are they built? In preparation for my tutorial on how to make a no-load tone pot, I dissected a couple pots (the same Bourns and CTS pots I’ve been looking at in my other videos). In this video, I explore the details of pot construction and how they […]
In this video I demonstrate how to modify a tone pot to be no load, for true bypass. The change in brightness is subtle, but worthwhile. Don’t be afraid to open up your pots and have a look – it’s pretty easy to do. But be forewarned, some pots are easier than others to put […]
This is a quick video comparing linear and audio/log tapers for a tone control. I’m comparing a Bourns 500k audio taper pot (PDB241-GTR01-504A2) with a Philmore PC27 500k linear taper pot. The capacitor is a .022uF Orange Drop (225P100V 223K). I’ve wired the neck pickup directly to the jack with the tone pot in parallel, […]
