Reviewed under Amazon's Vine program - I have no affiliation with the supplier, manufacturer, Amazon or any of its subsidiaries.Having used Musiclily's Pro pots in the past, these are superb quality pots to rival CTS at a fraction of the cost. Supplied with all fixings including double nuts and the ubiquitous free plectrum, the shaft on these has a sensible turning force so it doesn't spin like a windmill in a gale unlike some brands.Tested with an uncalibrated meter, the pots are almost dead-on the stated rating of 250k. The linear is, as expected, linear, and the audio taper pot, while being almost definitely a pseudo-audio taper arrangement, is close enough for all but the mot discerning of cork sniffers.These can also be easily disassembled should you wish to mod the carbon track for Zero Load, for example.Excellent value, quality and highly recommended.
