These are the highest quality Potentiometers that the CTS Corporation manufacture.
WD® Music Products developed these high-quality potentiometers with CTS® to offer you exceptional performance in electronics for your Les Paul and other carved-top instrument requiring the longer 3/4" bushing/shaft length. These are NOT the same CTS pots that other companies stock and sell. These are developed using 9% +/- tolerances and a value at 10% over the stamped, standard 500K rating (550K). This ensures you not only optimum performance but guarantees your potentiometers will always be at least the value stated unlike many others using 20% tolerances where you can be over spec but in most cases way under the specifications you need to ensure good tone from your pickups. They added brass components and a high-quality long-life wiper versus what comes standard on most run of the mill pots to ensure long life, quality and consistent performance.
Here at Atlantic Custom Guitars, we have gone one step further. With this set, you are purchasing a set of 4 handpicked 550k CTS Pots with a 5% or less tolerance. We buy these pots by the 100 pack and then we hand measure every one of them and split them up into either 525k or 550k which allows us to offer even closer 5% tolerances on both the 525k and 550k.
You are purchasing a set of 4 of the best CTS Pots on the market (These are not your standard CTS Pots which have a 20% tolerance). Each pot comes with 2 washers and 2 nuts.
Before I ship, I measure your pots and mark them with a V or T (Volume or Tone). For the best tone, your volume pots should have a higher value than your tone pots.
Important Specs and Dimensions:
- Tolerance = +/- 5%
- Value = 550K Ohms
- Can Size = 15/16 in. radius X 3/8 in. height
- Bushing Threads = 3/8-32
- Bushing Height = 3/8 in.
- Shaft Type - split
- Shaft Diameter = .238 in (6.0mm)
- Spline Count = 24 (NOT metric)
- Hole size requirement = 3/8 in.
PLEASE NOTE. These Pots need a 3/8" diameter hole for installation. Most Epiphones and Import Guitars have a smaller hole of 8mm as standard in the guitar body, so there is a good chance that you will have to enlarge the 4 pot holes in the body to 3/8".
Also, Epiphone Knobs (18 spline) won't fit USA spec pots (24 spline) like CTS, so you will most likely need new knobs.
