What does B mean on potentiometer?
Table of Contents
Potentiometers made in Asia and the USA are usually marked with an “A” for logarithmic taper or a “B” for linear taper; “C” for the rarely seen reverse logarithmic taper.
What is B in b10k potentiometer?
In Europe, A means lin (linear), B log (logarithmic) and C anti-log.

Is B log or linear?
Marking Codes

---|---|---|
Linear | LIN | B |
Log / Audio | LOG | A |
Anti-log | – | – |
What’s the difference between A and B pots?
A-Audio:usually used for volume. B-for tone.
What is the difference between A and B pots?
Generally, A is used for both tone and volume, but you can use B for tone if you want.

What’s the difference between 250K and 500K pots?
The rule is: Using higher value pots (500K) will give the guitar a brighter sound and lower value pots (250K) will give the guitar a slightly warmer sound. This is because higher value pots put less of a load on the pickups which prevents treble frequencies from “bleeding” to ground through the pot and being lost.
Are audio pots logarithmic?
To compensate for the ears logarithmic behavior, audio taper pots were developed. While it is called logarithmic, it is actually an exponential curve (the opposite of the logarithmic behavior of the human ear).
Are audio Pots A or B?
I have learned that tone pots are designated “A” and volume pots are designated “B”.
Are Bourns pots better than CTS?
CTS has a decrease from each level of around 5% and Bourns has a slower rate of around 2%. At this point, I am assuming I lost a lot of people by using percentages to talk about this Voltage Divider’s taper, but in simplest terms the Bourns is louder.
Why does Gibson use 300k pots?
“The resonant peak frequency of most HBs is usually around 5k to 7k. Gibson went to 300k pots in the early ’80s to fatten up the tone of their guitars, it’s not as though 300k pots are cheaper or anything.”
What is the difference between linear and audio potentiometers?
Linear pots will give a uniform decrease in volume/tone (you will notice more of an effect on each control knob setting) whilst audio will give a more instant (quicker) increase or decrease in volume or tone. If you gig a lot, audio may be better for a quicker boost while on stage.
What is the difference between a pots and B pots?
500k “A” would denote an audio taper pot, and the “B” suffix would denote a linear taper pot. The only difference is the taper of the pot, or “how gradually it rolls off”. Most manufacturers use either (2) audio taper pots for volume + tone or would use audio taper for volume, and linear taper for tone.
