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…

I heard about the Emerson potentiometers. The usual guitar shops did not carry them so I found them in My Stewart McDonald catalog . And within four days I was using them on my favorite bass guitars...

noisy - loose shafts

By


Before I even got the guitar completely wired, I noticed the problem. A few others have reported this same problem, so it's not just me (should have read through ALL the reviews before buying). These look like nice pots, I assume they do what they're supposed ta (I'll know when I finish wiring up the guitar) but as soon as I installed them into the guitar and tried turning the knobs I noticed how mechanically noisy they were compared to the old pots that they replaced. I installed these into a Jackson guitar which had one vol and two tone pots. The old pots (not sure if they were OEM or not) had a nice smooth and sturdy feel to them. But these have rather loose shafts that make a lot of "clicking" noise when turning. It's more than a little obvious. It's VERY obvious. I'm sure when you're standing in front of a Marshall stack it's unnoticeable but in a quiet room, it's really obvious. At this point I'm considering removing them and replacing them with something else but I'll give it some time before I make a decision.

Having said all that, I get why others are generally happy. They're "faster" than some of those stiffer, sturdier versions. That obviously means more to those satisfied users than some mechanical noise. I worry that this mechanical noise will travel right straight into the pickups and out the guitar. Will know more about that soon. I guess use your best judgment but if the "feel" of the knobs are paramount, I'd look elsewhere.

Going from 500Kohm to 1 meg gave the Parson Street bridge pickup a bit more punch. Just what was needed. These Pro potentiometers are magnificent.

Work fine :D

the taper is very quick, not tight like a CTS pot. Easy to work with, great bright sound with the pickups and guitar I used them on. Would recommend these over the plain CTS pots they sell.

The Pots you want!

These designed for Emerson, CTS POTS are fantastic. Mine are within 4 percent of the 500k rating which is exceptional. If you want a POT that the tolerance is excellent, the Emerson pro POT is it!

Not as loose as Bourns, not as tight as standard CTS. I have ruined std CTS split shafts trying to press on a knob. I like the brass shafts on these.

And they play well

I used both of these potentiometers to replace the original ones in my guitar. They worked out better than great.

The best taper ever!

By

Verified Buyer


I have tried all sorts of different versions of CTS pots, but these absolutely are the best. The taper is very smooth and even which allows you to find every subtle nuance on your volume control. This is really useful if you play "on the edge" of amp overdrive, or you use fuzz pedals. Top marks to Stew Mac for stocking these little marvels, they're gradually going into all my guitars!
