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.

The cure for obscure pots!

Got a non-descript crackling volume or tone pot ? Fire up the soldering gun, remove the small round things that are disguised as potentiometers and replace the ridiculous junk with Alpha Controls Pots. Case closed.

Great All Around Replacement Equipment

I have used many of these components at my repair shop. They work as well and sound as good as any others. Perhaps the best endorsement, I have never had one of these returned for replacement/problems. In once and out once, that is my shop motto.

After my prior bad experience, Spencer from Stew-mac customer services got in touch and offered me a replacement set. They even sent it out super quick via DHL worldwide express to Singapore where I am based. Top-notch customer service, super-quick response and my SG with 50's wiring sounds superb. Huge thanks and massive shout out to Spencer and the Stew-Mac team!

Not a bad alternative for the price.

I go back and forth with different brands of potentiometers. Generally, I still prefer to use Bourns pots when I can find them at a good price and usable quantity.

For coarse, knurled potentiometer shafts there's not many other choices than Alpha. My main issue with Alpha is the tolerances and tapers of these are somewhat inconsistent. Though, the quality is on par with, if not better than CTS. The CTS parts I've gotten over the last 5 years has not impressed me. Especially for the price, Alpha a great alternative.
