Audio taper potentiometer

Glossary Term: Audio Taper In a potentiometer, taper refers to how the resistance varies as the pot's armature is rotated (or, for a slide pot, as its wiper slides; or for a solid state pot like the DS1802, as its input voltage is varied).

What is the difference between audio taper and linear taper 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.

Should tone pots be linear or audio taper?

Volume pots should be linear and tone should be audio taper. Most people suggest the opposite because they are confusing an amplified circuit with an RC circuit.

Is audio taper the same as log?

The most used non-linear taper is the logarithmic (log) or audio taper. This is mainly used for audio volume control to obtain a more natural, "linear" perception in sound intensity change when you adjust the volume.

What is the difference between 250K and 500K pots?

What is the difference between 250K & 500K pots? Either 250K or 500K pots can be used with any passive pickups however the pot values will affect tone slightly. 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.

What's the difference between A and B potentiometers?

Whats the difference between A and B pots ? What is supposed to designated to A and what to B please ? The general convention for pots is that A is an audio/log taper and B is linear. For smooth control of volume, you should always use an A type audio/log taper pot.

Can you use the same pots for volume and tone?

A Tone Pot is nothing but a regular pot, with a capacitor soldered to it. A Tone Pot will work the same way as a Volume Pot, but just a little different. Instead of sending the entire signal to ground, the tone cap helps by sending only a part of the signal to ground.

Does Gibson use linear pots?

Save for some occasional odd models, they've use 300k linear volume pots with all humbuckers for the last 36 years to the best of my knowledge. The only 500k audio volumes I know of are in the custom shop guitars, and perhaps the R series (though I'm not sure here) because they are vintage correct.

Is audio taper linear?

Linear tapers can be good for adjusting lighting through light dimmers or for motion control. Non-linear tapers are often referred to as a logarithmic or audio taper. These are most commonly used for audio volume control.

What is the difference between a250k and b250k pots?

The "A" is an audio taper pot, used for volume controls. The "B" is a linear taper pot, usually used for tone controls. Either will substitute in a pinch for the other, with a somewhat different "action" when the knobs are turned.

What pots to use for volume?

Generally speaking, to control volume, humbuckers should be paired to 500k pots, while single-coil pickups should be paired with 250k pots. A 500k volume pot offers twice the resistance to the current flowing from the pickup to the output jack versus a 250k pot when turned up to maximum.

How do you tell if a potentiometer is linear or logarithmic?

Use a multimeter. At "0" resistance should be 0, at "10" it will be whatever value the pot is i believe (250K, 500K etc) and then measure at "5". If its half of the "10" value, then its linear. If its much smaller than half then its log.

What does the A and B stand for on potentiometers?

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 are two types of taper in a potentiometer?

Potentiometer Taper Charts

Linear Taper. = total resistance of the potentiometer, measured between the potentiometer hot and cold lugs.
Audio Taper. = nominal resistance of the potentiometer, measured between the potentiometer hot and cold lugs. ...
Reverse Audio Taper. ...
M and N Taper (Blend-Balance)

Are audio pots logarithmic?

Audio Taper Potentiometers are log tapers, which are potentiometers that change resistance logarithmically as you turn the wiper. This is crucial for audio applications because logarithmic change in resistance, not linear change, is what is desired. Ours ears perceive sound in a logarithmic fashion.

Do pots make a difference on guitar sound?

Guitar pots influence the level of how bright and dark your guitar sounds not affecting core sound. Low-value Pots (250K) sound warmer due to less resistance in the signal. In contrast, high-value pots (500K) sound brighter as they include stronger resistors that retain higher frequencies.

What pots to use with humbuckers?

250K control pots are the usual choice for single coil pickups. 500K control pots are the usual choice for humbuckers. These "K" numbers are the resistance ratings (kOhms).

How do you choose a potentiometer for volume control?

In general, you want the potentiometer to be as small as possible without putting too much of a load on the source. A quick rule of thumb for selecting the resistance of a potentiometer is that you want the input impedance to be an order of magnitude (10 times) higher than the output (source) impedance.

What is the difference between A500k and B500k pots?

A B500k has a linear taper, which means the change is continuous from one end of the control to the other (think of that as a straight line). An A500k has a logarithmic taper which generally work more like a curve from one end to the other, with most of the control happening around either side of the center.

What is a Type B potentiometer?

Type B potentiometer refers to the linear taper. Type B potentiometer also called as a linear potentiometer. Linear taper potentiometers are the potentiometer if we turn the wiper of the potentiometer its resistance will change in a linear fashion.
