A few weeks ago i bought a used Peavey Databass combo--450 watts, 15 inch Black Widow, 70 lbs. It was in pretty good shape but missing a couple of knobs. So three or four days ago I e-mailed Peavey parts department asking how much the knobs would cost. Well today in the mail I got both knobs--No Charge!! Incredible customer service. I've bought Peavey stuff for years. Will I continue to buy and recommend Peavey? You bet!!!
