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.

I use these for repairs and custom builds. Very good controls at a decent price.

A great value and quality

Worked perfectly in my 2013 Ibanez S421. Great build quality and feel to them. Very noticeable tone difference. Loved the small tab on the top of the pot near the shaft. Gives a solid grounding point to the copper foil in my electronics cavity. For Volume control they are much better than the stock and for tone applications with a 223 capacitor they are very dynamic.

A good buy but you kinda need to buy them by the dozen

I started using these simply because customers who bring import guitars to me can keep their original knobs. Just to save the customer a few bucks if I can. But you know what? I like them. You do need to buy at least a dozen at a time though because of their tolerance. Measure them as you get them and save the ones that measure above 500K for guitars that you want to brighten up and save the ones that measure lower than 500K for guitars that are too bright. In the grand scheme of it all, they are a good buy. Pictured is a harness I made for a customer’s semi-hollow body guitar using these pots along with a short Switchcraft switch, long Switchcraft jack, vintage braided pushback wire, Orange Drop caps and treble bleeds I made using components from another vendor. This harness woke that guitar up in a very big way... Oh, one more thing. After building a harness or just replacing a pot or two, always clean them with a quality cleaner such as Caig DeoxIt. Let the cleaner dry fully then lube the pots with a quality fader lube such as Caigs DeoxIT Fader F5.
