Emerson Pro CTS Pots

About This Item

Lower drag, tighter tolerance and smoother taper. Individually tested control pots for demanding pro guitarists, developed by Emerson in cooperation with CTS.

  • 8% tolerance
  • Smooth, even volume taper from 1 to 10
  • Low drag for the smoothest feel

Why a "pro" pot? Emerson's Mitch Ingram explains:
"Pro CTS pots from Emerson Custom were designed to be the premium choice for the discerning guitarist looking for optimum performance and tonal response from a guitar potentiometer. They feature a longer-life brass shaft and bushing, and a tighter ±8% resistance tolerance. Each and every Emerson Pro CTS pot is hand tested to ensure that it meets or exceeds our stated tolerances. The proprietary custom audio taper was specially designed for a very smooth and accurate response when you roll up and down on the controls. Crank your guitar up to 10 and the volume swells all the way—no abrupt flattening to choke your playing style."

Erick Coleman, guitarist, repairman and StewMac tech advisor, adds:
"I use Emerson Pro CTS pots and really like the way they perform, as do the clients whose guitars I've installed them in. Precise, and with an even taper. No sudden jumps or cuts as you turn the dial. Low drag means they're easier to turn, giving you faster control. The bottom of the pot has the vintage look, too."

Emerson Pro CTS pots are available with fine-knurled split shaft, or with smooth shaft for set-screw knobs. A long-shaft split-knob 500K-ohm version fits Gibson Les Paul® and similar carved-top solidbodies.

Each pot includes a flat washer, lock washer, and two hex mounting nuts for custom height adjustment on a pickguard or control plate. 3/8"-diameter (9.52mm) mounting hole required.

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 (attenuates) 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.

Upgrading control pots: choosing the right pots and knobs

Lots of low-cost guitars play great, even though the manufacturers cut costs on hardware and electronics. Swapping out your control pots is an easy mod with big results. Erick Coleman shows you how to avoid trouble…

Stew Mac: 5, Emerson Pro: 1

First a quick explanation of my rating. Stew Mac gets 5 stars for customer service. They were very helpful when I explained my issues to them both before and after this purchase. I would, and intend to, buy from them again in the future. These pots however are just not for me. I'd give them 1 star, so my overall rating averages to 3 stars. Now here's why...

I have a Gibson Melody Maker Special with 2 P90 pickups. For this setup they used a 300k volume and 500k tone. The guitar sounds good, but the pots were having trouble staying clean, so I opted to replace them. Stew Mac directed me to try a 250 and 500k since 300k is a bit of an oddity. After reading the description of these Emerson Pros and their promise to have a very smooth taper, I, of my own free will, ordered a set.

The 250k volume worked fine in terms of having a very smooth taper, but was too loose for my liking. I kept turning myself down by accident when strumming. The 500k tone, was also loose, but out of my strumming swing so that wasn't a problem there. It's issue was that the taper was not smooth at all. 1-4 was where most of the range could be found on the knob. 4-10 did almost nothing. Since I needed the guitar for a gig, I cleaned up the old volume pot as best as I could and replaced the tone with a regular CTS 500k I got here in town. It's worked fine ever since.

Final thought, Stew Mac is still awesome and so are regular CTS pots. They are tighter, smoother, and a few bucks less. Save your pesos and get a standard CTS. Emerson Pro is a no go for me.

Loose is good??

By

Verified Buyer


I bought these pots over the standard 450G CTS pots thinking I would be getting a better product. The shafts are loose in the barrel bushing and more noticeable after placing the knob on. They do rotate quite freely! And on another note, they react like linear pots not taper in my observation.

Great Pots

Smooth taper all the way. Takes a little getting used to after standard pots that don't start to work until about 8

Smooth as silk

I bought just the one pot for the volume on my Strat copy and am very pleased. The rotation is as smooth as advertised and the consistency of resistance is all the way to the ends - smooth control up and down.

Put them in a 1982 Epiphone (rebadged as Gibson) SG Special II. They work great, used a 47 tone cap.

Easy to turn and sound great.

I replaced the standard CTS 500k pots with these Pro CTS Pots on my Epi Les Paul. They sound just as good as the std CTS pots, but rotate much easier. The std pots have a thicker lubricant in them that creates a drag when turning. These Pro CTS pots are very loose so I can make adjustments easier while playing.

Poor quality control

By

Verified Buyer


Echoing others dissatisfaction, I must say I feel duped for spending so much on what is clearly an inferior product. I’m too far past purchase date, and probably burned the receipt or I would send them back soldered and all. Shaft is so loose that moving the guitar cause them to bobble visible and audibly. Smooth turn but so loose as to be unusable. Will not touch again.

EMERSON 500K GUITAR POTS

I will finally be able to use pots with tight tolerances. Most of the pots I've installed in my older guitars strayed out of (resistance) SPECS. I hope StewMac continues to sell this particular brand. Emerson guitar pots rock!
