Details

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   3/8" x 32
Threaded portion height   3/8" (9.52mm)
Required mounting hole diameter   3/8" (9.52mm)


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 for thin guitars like SG

By fret_man from Bartlett, IL
(Customer's Reviews) Sunday, September 25, 2011


These standard shaft single-ganged pots fit thin guitars like the SG. Quality is good enough - no complaints, but nothing special that I can see. I think a linear taper option would give a better feel for a tone control. With these audio taper pots, treble cut doesn't occur until the last 20% of the rotation.

Pots in a pinch

The Alpha pots are ok in a pinch. Like some of the others have written the CTS pots are much better. I used these pots in a project because I could not find any local. Other pots would have taken longer to get to me and I was in a hurry to give it try and knew that StewMac would have them here the next day. StewMac like always was GREAT to deal with. FAST shipping and delivery.

Go with CTS Pots

After installing these pots in one guitar and CTS in the other I can tell you the CTS are worth the extra money.

Works

I thought about the function of "tone controls" on Guitars, and realized why I hardly ever used them. They are mostly just high-cut filters. After much thought-out selection of body and neck woods, string support hardware, pickups and amplification, you want the tone of your guitar to stand out. With a one mega-ohm pot for your tone control, you can more thoroughly eliminate the "ground-bleed" allowed by the capacitor. Sometimes this "ground-bleed" is desireable. With heavy-bodied guitars equipped with humbucking pickups, it usually isn't. If you really want that "Les Paul" project to "spank" and "chime" give these a try.....you will be IN LOVE.

Would have preferred CTS pots, but they do the job for now.

ALPHA!!!

It`s ALPHA!!! Creak and rustle of use. Traditional Taiwanese pots. I'm disappointed. I expected to see Japan, Korea, USA, but not Taiwan. They definitely need to lubricate.

It's Alpha.

It's alpha-branded control pots, so they are in cheaper range of similar products. I prefer using CTS pots, too bad Stewmac doesn't carry them.

quality product

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 Ken Landis from Gap, PA
(Customer's Reviews) Sunday, August 07, 2011


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.

Control pots

By 2bike from Brampton, ON
(Customer's Reviews) Sunday, August 07, 2011


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.
