Alpha Control Pots

About This Item

Great price!
Alpha potentiometers are among the world's most widely used guitar tone and volume controls.

These are the familiar pots we've supplied for years in 25K, 250K, 500K, and 1 meg-ohm versions, plus a long-shaft 500K version for Les Paul style carved-top solidbodies. Great prices, too—luthiers and repair shops can save big on orders of 50 or more.

Each pot has an aluminum split shaft that fits a coarse-knurled (18-spline) knob.

Alpha pots are audio taper with standard ±20% resistance tolerance. Each pot includes a flat washer, lock washer, and two hex mounting nuts for custom height adjustment on a pickguard or control plate.

#3755 25K-ohm
For controlling the volume or tone of active pickups, or for use after the preamp of a piezo-saddle transducer bridge.

Shaft diameter 6mm split shaft, coarse knurling
Thread   M8 x 0.75
Threaded portion height   3/8" (9.52mm)
Required mounting hole diameter   5/16" (7.94mm)


#0128 250K-ohm & #0130 500K-ohm
500K pots are standard controls for humbuckers, and 250Ks are usually used for single-coil pickups. A 250K gives a slightly warmer tone than a 500K, and bleeds off (attenuates) some of the high frequencies to ground. A 1-meg pot attenuates even less than a 500K—try one if you want to hear your guitar "wide open."
Shaft diameter 6mm split shaft, coarse knurling
Thread M8 x 0.75
Threaded portion height 3/8" (9.52mm)
Required mounting hole diameter    5/16" (7.94mm)


#3482 500K-ohm, long shaft pot
For Les Paul and similar solidbody guitars.
Shaft diameter 6mm split shaft, coarse knurling
Thread   3/8" x 32
Threaded portion height   3/4" (19.05mm)
Required mounting hole diameter   3/8" (9.52mm)


#3481 1 Meg-ohm
Get the most out of your guitar with a 1 Meg-ohm pot. All pots bleed a certain amount of the signal to ground, this "attenuation" can be used to warm the sound of your guitar's pickups, but you can also run your guitar "wide open" with these 1 Meg-ohm pots!
Shaft diameter 6mm split shaft, coarse knurling
Thread   M8 x 0.75
Threaded portion height   3/8" (9.52mm)
Required mounting hole diameter   5/16" (7.94mm)


Which pot value should you choose?
500K pots are standard controls for humbuckers, and 250Ks are usually used for single-coil pickups. A 250K gives a slightly warmer tone than a 500K, and bleeds off some of the high frequencies to ground. A 1-meg pot bleeds off even less than a 500K—try one if you want to hear your guitar "wide open."

1-meg pots are also ideal for piezo pickups, as the ultra high impedance piezo element is more adversely effected by conventional, lower-value pots than magnetic pickups.

25K pots are for controlling the volume or tone of active pickups, or for use after the preamp of a piezo-saddle transducer bridge.

Replacement Mounting Nuts and Lock Washers are also available.

When I got them out of the box I was worried because they felt a little scratchy. But, I have installed them and have not been disappointed. They are smooth, accurate and noiseless. I will not hesitate to use them again in future projects.

I had to replace pots for a repair, and even as a complete beginner, these were no trouble.

This is a good quality potentiometer. I make it a habit of flushing new potentiometers prior to putting them into the circuit, The STEWMAC pots have not let me down yet.

Blend Pot

By
(Customer's Reviews)


Installed on a Epiphone Viola Bass. I replaced one of the two volume pots with a blend pot to control pickup selection. I followed the wiring diagram as provided on the Stewmac website. With the pickup height properly adjusted, there is no inconsistency in volume across the sweep of the pot. I works perfectly as advertised. I also switched out the remaining controls with new audio taper pots from Stewmac and an increased value 0.1mf capacitor. Improved control of tone is now very much at my fingertips.

I Meg Control Pot

By
(Customer's Reviews)


I bought a new loaded H/H strat pickguard off eBay. It was a very good deal and the product is very attractive and well made, but I had hoped the pickups would be more along the lines of PAF strength but they turned out to be hotter, hence a bit muddy for my needs. I tapped the coils by using a Stewmac 500K switch pot and, although it added versatility, it did not solve the issue. Stewmac support suggested I try 1 MEG pots for both volume and tone. It made sense to try this before investing another $150 in pickups, so that is what I did. Well, it worked! The pickups are much brighter with 1 Meg pots. Since there is currently no 1 MEG switch pot available I simply added a Stewmac mini-toggle switch for coil tapping. I am very pleased.

Thanks AGAIN to Stewmac support for their fast, courteous help!

disappointing

The 500 K pots tend to get stuck up after a while and that grinding feel also makes me unsure if the shafts would not detach in the long run.

Very scratchy

By
(Customer's Reviews)


Ordered two 500K pots, measured them both and they're both about 570K, which should be close enough for my purposes. I was very disappointed when I first took them out of the package and started playing around with them, because there's a noticeable grinding feeling that you get when turning the pots. I'll install them for now, but don't know what kind of longevity to expect with this grinding feeling.
