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.

By

the alpha pots are not very forgiveing. they will burn up if you get it to hot or resolder it multiple times. if you are new to soldering spend the extra bucks and get the cts pots. if not you cant beat the price.

Waist of Money

By
(Customer's Reviews)


I bought some of these pots and they are a Big Waste Of Money. The volume pots don't work and after hooking-up to a guitar, they sound as though they are full of sand. It would cost me more to send them back than they're worth. (driving 12 miles into town to the post office and shipping)I shouldn't even rate them a star because they are junk. I would not waste money on these. Save yourself a lot of time and aggravation and steer clear of these so called pots.

went into this fun project

By
(Customer's Reviews)


this was a tradein at my brothers guitar store, rebuilt it, gave it a crazy paint job, put in my soap bar pups I made from StewMac kits, and used these pots...for a cheap little guitar, the sound is awesome because I used good electronics and my manually hand wound pups..the pots are in that equation of good sound..with everyone that buys my pups, I encourage they make sure they have high quality pots

Better sounding pots...

By
(Customer's Reviews)


Installed these as replacement for the stock pots that came with a chinese made palmer 6 string bass. Now the bass is gig worthy, 'cos the sound is clearer and controls are precise. I still have to address a noise problem that happens when turning down the tone control.

They get the job done.

Ive used these in several guitars without any problems. They do sound like they could use some internal lubrication though, but they turn easily and sound fine.

Good for thin guitars like SG

By
(Customer's Reviews)


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.
