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.

Good quality pot

Been using these for our lower-cost builds. They do a fine job and have low failure rates. They sound good.
Be aware they have a different shaft diameter than the CTS pots...

Solid and Reliable

I use StewMac's 250K and 500K audio pots for repair and/or upgrade jobs on Asian-made guitars and basses. They're smooth, solid and dependable. Here's a recent wiring upgrade job on a Fender ST-33R Stratocaster (Japan). The stock Gotoh 250K pots were replaced with Alphas, and the customer says his strat has suddenly "come alive."

Not for a Guitar

By


Physically noisy, sounds like rasping a safe open when you turn the dial. I got 4, all turned out equally noisy so I'm guessing they make them this way. I later realized these are probably not for a guitar and for some other application. I think these might be ok in a solid body electric, but I would not recommend for semi or hollow body instruments.

I give them 2 stars because I have never heard any pots so physically loud before, but they do look well made. It almost makes a small echo effect you can hear.

I might put them in a small box and make a "safe cracker" game where that rasping could be useful for effect, but not in an instrument.

Alpha tone pot

By

Nice pot, good price. Smooth action. Used as tone control, cut the trace so at full treble the tone circuit is out of signal path.works good!

Work great minus the physical noise.

By


I bought a wiring kit for my '72 Telecaster Deluxe and the pack came with Alpha pots. There's a noticeable friction noise when you turn the pot, but for the price I can't complain.

5.0

Smooth, tension just right, reliable.

By

Verified Buyer


Alpha seems to have just the right tension on these pots. Not too stiff, not too loose.
I like to be able to roll the volume up and down with just my pinky at the beginning and ending of songs and Alpha's let me do that. I've immediately replaced stock pots on guitars that were so stiff I literally had to grab the knob with thumb and forefinger in order to turn them. That's too stiff.
Alphas' are "Goldilocks" pots for me!

Mechanically Noisy

The pots function once soldered up, but make a lot of physical noise.
