Preset Potentiometer (Trimpot)

A Trimpot is another type of potentiometer that comes in small package. It has three leads and can be easily mounted on breadboard or perf board for quick prototyping. The value of the pot can changed by varying the knob on top of it.

Hey everyone.

It’s quick restoration time! 

Back when I took my trip to Washington state to pick up that collection of vacuum tubes, I also grabbed a bunch of potentiometers. Included in that collection were a couple really old porcelain ones. As you can see from the pictures, they were in pretty bad shape.

As I mentioned in my previous post, it’s been a rough couple of months and I needed something to do that I could finish quickly for that sense of accomplishment. So a few nights ago I decided to try to restore one of them.

I started by figuring out how to take it apart. The knob had 2 set screws which had rusted to the point they were fused with the shaft. At first I tried drilling out the screws to see if I could get the knob to loosen, but that didn’t work. So I ended up just using a hacksaw to cut through the shaft. This took almost half an hour. I need to get a new hacksaw blade. :\

Most of the metal parts had rusted pretty badly and the spring that held the wiper (bent copper part in the last pic) to the contact (copper ring under the bent metal part) had disintegrated. My wife had given me some steel wire at some point (I don’t remember why) and I was able to use that to create a custom spring.

Then I had to drill out the rivet that held the contact to the porcelain body. After that I de-rusted all of the parts and polished up the copper. Lastly I put the whole thing back together and now I’ve got a working 2500ohm potentiometer that I can use for... something. Huzzah!

3296 Trimmer Potentiometer

Trim pots are also known as preset potentiometers used for adjustment, calibration and tuning purpose in circuits. They are easily mountable on PCB boards and adjusted by a screwdriver. The resistive track is made up of carbon composition or cermet. When replacing with normal potentiometers, remember their life span is not so long. 

Among all the accessories that you can add to your electric guitar, a high-quality potentiometer set is an extremely valuable addition. Regardless of whether you are refurbishing your existing equipment or building a custom-made electric guitar from scratch, choosing the appropriate potentiometers for your guitar will help you achieve more accurate control and better tonal response. From Exotic Wood Zone, you will be able to buy high quality guitar parts to make your custom-made guitar with exotic wood look great.

Why a Potentiometer Matters in a Guitar

Potentiometer is a device that is a variable resistor that is utilized to control your guitar's volume and tone. The knob is turned in one way or the other and this will adjust the electrical signal from the pickups that enable the players to affect their sound in the required manner. The best thing about buying a good set of potentiometers is that because they are of higher quality you will be able to control the sound more easily and your potentiometer will last longer.

There are many reasons why the guitar manufacturers choose cts potentiometer – its reputation, precise resistors, and comfortable rotation among them. The combination of these qualities makes it popular with both luthiers and hobbyists.

Linear Potentiometer vs. Audio Potentiometer

When selecting a linear potentiometer, it's important to understand how it differs from an audio (logarithmic) taper.

Linear potentiometer allows you to change its resistance evenly, making it suitable for those who need constant adjustments. Most people prefer linear pots for controlling the tones while the audio taper pots are preferable for controlling volumes because they provide a better response of human ears to sounds.

Your choice will depend on your style of playing, configuration of pickups, and even preferences of each individual person. The best builders try their hands at different kinds of pots to find the best compromise between responsive and tonal control.

Choosing the Right Guitar Pots

There is a great difference between different types of guitar pots . The resistance levels such as 250K and 500K have an important effect on the tone of the guitar. Low resistance gives you warm tone, whereas the high one keeps the high tones in the pickups of your guitar.

When selecting guitar potentiometer components, consider:

Pickup type (single-coil or humbucker)

Shaft style (split or solid)

Resistance value

Build quality

Long-term reliability

High-end cts potentiometers are known for their reliable performance and ease of use; hence, many people like to use them when upgrading their guitars or building one.
