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.

Beware

By

Verified Buyer


I bought these because they were more expensive and they advertise them as being more accurate. The problem is they have a very loose feel. Not much resistance when you turn them. I personally hate that. I like the pot to have a tight feel. I bought the cheaper CTS pots and they have that tight turning resistance. I checked them with my ohm meter and they were very close to specs. There's my two cents worth

I will be installing 3 of these in my older Jazz bass with a new capacitor and jack. I have been using CTS pots for many years, they never let me down.

As always, fast service and shipping from Stew Mac! Although these pots measured within their advertised specs (1 at 528, 1 at 533 ohms) I was disappointed with the performance. The taper was not particularly good and much too loose which made it more difficult to adjust volume or tone. I replaced them with a different set of CTS pots.

I bought a first quality US made Tele style guitar with enormous soapbar looking single coil pickups from southern California. I got very little volume out of it until I ran the volume up to full volume. I contacted the product support, described the problem and without hesitation, they sent me a replacement pot. I put a fluke meter on it and found that I would get the same volume taper out of the replacement pot. I ordered the Emerson Pros, first looked at them on the meter and saw a huge difference in taper and installed them in both positions. What I got was a very nice even predictable volume gain throughout the entire sweep. Now I can do really nice predictable volume swells (Sweet Dreams) and tone is much easier to dial in.

Never use CTS pots again

I was using CTS Pro pots in some of my projects. I tried some Emerson Pro 500k pots in my one Les Paul and could not believe the sound difference. I play in a 50's/60's band and was looking for that certain sound. I paired the Emerson pots with Seymour-Duncan Seth Lover PAF humbuckers and .0047 orange caps with 50's wiring pattern. WOW...it is the exact sound I am looking for and have changed over all my LP's now to Emerson and threw out my CTS's.

Very well done Emerson...and thanks Stew-Mac for your quick shipping options.

Upgraded my MIM 50's Precision bass with a pair of these pots, along with the Emerson paper in oil cap and Fender's reissued 62 Precision pickups. This is now my favorite bass to play; hands down, the best sounding of all my basses.

I used regular CTS pots for years in all repairs but have now switched permanently to Emersons. They have a very smooth taper and the low resistance can definitely be heard for clarity. Mount Emerson pots in a guitar and they are there to stay, no worries!

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??

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.

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