I ordered two pairs of these 500k push/pull potentiometers, these will be installed in a Gibson Les Paul electric guitar. The packaging was very good. Measurement of the first pair resulted in an average resistance of 475k, easily within 5 of tolerance. The second pair averaged 485k, even better at 3. I would like to note the pairs appear to be matched, although they do not claim this on the product page. I will definitely do business again.
