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.

Better than expected!

In a recent project to mod my Epi LP Jr I replaced both volume and tone pots with these 500K pots. They are both super-noiseless and do what they are supposed to...guitar sounds great!

These are NOT 3/8" bushings. And how are you inserting a 3/8" bushing in a 5/16 hole?????

They work fine, and had the exact shaft length that I needed. They are a bit noisy though, which gives it a cheap feel. It would have been nice if Stew-Mac offered a higher-quality version of the same part.

I have a 5- or 6-year-old, dual-humbucker Fender whose volume and tone pots started scratching at an early age. These 500k-ohm potentiometers soldered in without any undue troubles. They're smooth and silent. I highly recommend them.

Long shaft pots

These are very hard-to-find pots, so I must thank Stewmac for them. Hardly overpriced

Good quality pot, but hard to solder on the case for the ground wires. Tried several Weller pro soldering station, & different types of solder.

scratchy

These pots are good the only drawback is they need some lubricant. You can't hear it while your playing but whenever i turn them I kinda cringe. I can feel it more than anything. Overall good pot though

1 meg pot

My soldering skills have diminished. did I get these pots too hot? I doubt both of them. Not enough control, from 10 to 9 volume drops drastically. I expected a better controlling pot. You would think coming from a guitar part place they would have worked better. Plan on changing them soon. Might work for you.

It is a good pot for the job. Thank You StewMAc. Antonello
