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…

Excellent!

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!

Nice smooth feel

By

Verified Buyer


This is a pretty good pot, and it has a nice smooth feel. Installation went smoothly, and there were no problems. I measured 4 of these pots before installing them ( 2 500K and 2 250K), and they were within tolerance ( 8% ) (480K, 482K, 224K, 228K). I have measured the Fender branded CTS pots, and they have all been much closer to the rated value (+ or - a few ohms). I guess I expected closer readings from a pot labeled "Pro". Overall, I am very happy with these pots.

Great upgrade for Les Paul Studio

By

Verified Buyer


I upgraded the pots on my 1997 Gibson Les Paul Studio with Emerson Pro CTS 500K. The stock volume pots were 300K, and the new pots brought out the "Les Paul" tone I had been lacking. I got two matched sets, one set mesured 501K and the other set measured 496K, much tighter tolerances than the advertised, also, having matched volume and tone pots allows me to be more precise in dialing in my tone. I also upgraded the capacitors to Sprague Orange drops and wired the vintage tone circuit. I highly recommend these as upgrade pots!

Great for upgrades

By

Verified Buyer


I used two of these Pots, one 500k and one 250K to upgrade the volume and tone controls on a new Epiphone Joe Bonamassa limited edition Firebird 1 and it has made a very noticeable difference. The controls the guitar came with were not bad, but these Emerson Pro CTS Pots have turned a very good guitar into a great guitar. I highly recommend them for any electric guitar upgrade.
