I ordered quantity 4 of a 500k volume control, received 1 500k, and 3 250k, it gets worse. Tried calling them, no answer, called 12 times over 3 days, no answer. Emailed them 3 times, over 2 days ago, no response. Faxed them over 2 days ago (Wednesday), no response. Meanwhile, my Les Paul, which HAD shows scheduled, is left in an unsoldered mess. I opened a dispute w/Paypal.... we'll see. I'll report outcome back here. THeir prices are ok, but not really, considering their sh*tty customer service and quality control (to date).... I did have orders years ago from them that were ok (actually, i better check potentiometer values on those!) ugh.
