Emerson Pro CTS Blender/No-load Pot

About This Item

Expand your tonal range!
Smoothly blend your pickups into your sound or remove the tone control entirely, giving your Strat the raw output of a "no-load" pot.

Seamless, intuitive blending
The Emerson Pro CTS Blender Pot has a custom audio taper specially designed for smooth and accurate response. Wire it to replace your Strat® middle pickup tone control, and smoothly blend your neck or bridge pickup into the mix at the 1, 2, 4 and 5 switch positions.

Get raw "no-load" sound
Add a full-throttle, no-load option by replacing your tone pot. Dial this pot up to 10, and it's removed from the circuit completely. Hear the full presence of your pickups, unaffected by loss of highs from your tone circuit. The capacitor and the pot are added back in smoothly as you roll off the control. The Pro Blender/No-load Pot has no detent, so the feel is click-free. This requires no special wiring, simply swap the pots.

    Low drag, tight tolerance and smooth taper.
  • Long-life brass shaft and bushing
  • 10% tolerance
  • 250K-ohm custom audio taper
  • Developed by Emerson in cooperation with CTS

"Pro CTS pots from Emerson Custom were designed to be the premium choice for the discerning guitarist looking for optimum performance. They feature a longer-life brass shaft and bushing, and a tighter resistance tolerance. Each and every Emerson Pro CTS pot is hand tested to ensure that it meets or exceeds our stated tolerances for smooth and accurate response."
—Mitch Ingram, Emerson Custom Guitar

"I use Emerson Pro CTS pots and really like the way they perform. No sudden jumps or cuts as you turn the dial. They're easier to turn, giving you faster control. The bottom of the pot has the vintage look, too."
—Erick Coleman, repairman and StewMac tech advisor

A great no-load tone pot, but less than ideal as a blender

By

Verified Buyer


This pot works very well as a no-load tone pot: In this application, when you turn it all the way clockwise it decouples the path to ground through whatever capacitor you have soldered to it, and thus prevents any of the high frequencies from being bled off to ground. Thus, when the tone control is at '10' (all the way up), you get the maximum sparkle and chime from your pickups.

The blender application works, but in the opposite rotation of a standard volume control. When it's all the way 'down' or turned fully counter-clockwise (i.e., at '0'), you get the maximum addition of whichever pickup you are blending in. As you turn the control clockwise (as would be 'up' for a volume control) this *reduces* the signal from the added pickup. When turned all the way 'up' or fully clockwise (i.e., at '10'), the signal from the added pickup is fully disconnected or OFF. For me, this is backwards and thus counter-intuitive.

Normally, as in a standard volume control, we think of a clockwise rotation as adding more of something, and a fully counter-clockwise rotation as turning it off. When used as a bender pot to fade in another pickup, this pot works in the opposite direction. So, while it does do the blending as advertised and does fully decouple the added pickup at at one end of its rotation, the rotation is backward from what would make sense for anyone accustomed to turning a typical volume control.

For the add/blend function, I have chosen instead to use a three-position toggle switch:
1) The first position is OFF (zero addition of the other pickup).
2) The second position is a partial blend (using a resistor of 120 K ohms or whatever you like that equates to a fixed position on the blender pot to allow a fixed partial addition of the other pickup).
3) The third position is is fully ON (the added pickup is connected in parallel with no resistor).

If you want more blend increments and intuitive rotation like a normal volume control, you could instead use a rotary switch (e.g., 5, 6, or more positions) with OFF (decoupled) as the fully counter-clockwise position, fully clockwise as the fully ON position for the added pickup, and then a series of different resistors on each of the in-between positions to provide different degrees of blend.

On a Strat, I've also included another switch for coupling my bridge and middle pickups in series when the standard 5-way switch is in the bridge pick-up position. In combination with the 3-way blender switch, this allows for a considerable range of tonal options, as the series setting affects both the normal bridge pickup position and the blended addition of the bridge pickup with the neck pickup. I then use the no-load pot for a tone control so I can maximize the transmission of high frequencies when desired, plus an active EMG SPC control (with bypass switch) to boost the mids when I want the extra kick that gives. This makes for a very versatile guitar with considerable tonal range.

Spin-a-Split

Used this for a spin-a-split on a T.V. Jones Power'Tron Plus. The taper was excellent. There was no massive drop off in volume or output. Very smooth as you spin from 0 to 10.

Emerson Pro CTS Blender/No-load Pot

By

Verified Buyer


I wired 2 Stratocaster guitars using the circuit for the Emerson Pro CTS Blender/No-load Pot and now I have the added features of being able to blend in the neck pickup when I select the bridge pickup as well as blending in the bridge pickup when I select the neck pickup, and there's more. This is an easy modification to do and it works very well and it's well worth doing.

Works, but is very sloppy/loose.

By

Verified Buyer


I put a pair of these in a recent Strat build I did. They work for taking the tone cap completely out of the circuit, and so allow a bit more brightness to come through, but the shafts feel very loose and there is noticeable wobble back-and-forth of the shaft, which leaves me worried about reliability long-term. This would get 4-5 stars if they had the precise feel of the rest of the CTS line.

Great for strat modifications

By

Verified Buyer


I frequently have customers with stratocasters that I recommend this modification to. You can replace the bridge tone knob with this pot, and allow a blending of the neck & bridge pickups. This gives a whole new world of options to your pickups selecting, and in my opinion is a must for any studio guitar.

Emerson CTS blend pot

By

Verified Buyer


Part was as advertised, but, I could not apply it to P-J Bass application....my bad for not researching enough to find it was for guitars with a 5 way switching system.
I ordered the Alpha blend pot, installed perfectly, and works great.

piece of junk

By

Verified Buyer


this pot, at least the particular one i got, is DRAMATICALLY BAD. its so loose that it practically move by itself if you move a lot on stage. and it feels "scratchy".the shaft WIGGLES so the knob feels like the whole pot was not mounted properly. but it is - its just the loose shaft in the pot itself. and it make noise when turning, like it was some years old and not used. the experience you get is practially "its bloody broken!". the worst pot I ever used.

Golden ratio for quality/price!

I love these pots. Emerson Pro/CTS quality is fantastic, and the no-load functionality is sublime.

I just wish these no-loads were offered in other ratings, or at least in 500k. 1M would be nice, too.
