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.

Everything you need in a pot. only drawback: the label indicating the value of the pot is small, and oddly positioned.

500K Long Shaft Potentiometers

By

Excellent for wiring pickups in a guitar with back cavity through wood top. I used them with 2 p90's going to a straight 3 way switch and the output of the switch to another 500 pot for tone with a .22kohm capacitor. With the switch on both pickups and bridge pickup loud, lower the neck pickup and there is no sound but just a small turn brings in the bridge pickup full. Great for swells.

Contrary to some of the other posts I read that lead me to order these pots, I found them to be worse than the chinese controls on my guitar. They created niose that wasn't there before and the physical construction was flimsier. One actually broke apart on installation. Internally was a very thin, light action slider on a metal resistance strip. Gone are the good old days it seems when pots were resistice material laid on the track and you needed a hammer to break them open. These pots were very disappointing. Ended up keeping the original chinese installed.

Needed another 500k mini pot and instead of ordering from Mouser, Allied, Newark or Antique as I do for most of my electronics, I decided to get it from Stewmac this time because I needed some other luthier stuff. The pot is exactly what I wanted and the price and quality are similar to the big electronics houses... great part.

the 500k-ohm mini pots are basically all I've used so far and I haven't had any problems with them. In my opinion they do what they are supposed to do, and so far they seem to last.

Purchased this to replace the factory linear taper on the master volume of my Fender Hot Rod Deville amp. Am very pleased with the results. Would have preferred a solid shaft, but this works great.

Did you ever order a cheap Chinese guitar and find good wood but junk electronics? This is what you need to fix it.
