Not in front of me yet, enquiring if known whether a batch of bad pots went
into them, or maybe a serious case of Pbfitis.
Only a year and a half old but for ages the owner has had to offset a
standing , non varying, L/R imbalance using all the pan pots but there is
also bad "scratching" of 5 of the channel sliders. Used in a personal studio
environment so no abuses at all.
