I've had my BKP Painkiller for a little over a year and a half now, and I love the thing, best pickup I've ever owned, but I've noticed(don't know if it's just my amp) that the pickup tends to sound the best in any drop tuning and sounds meh in E standard. It doesn't have that low end growl in E standard. I can get a nice rock tone in E standard, but nothing metal, but the cleans are the best in E standard... The best tuning I've found for this pickup by far is Drop C, gives it a nice bite.
Am I just weird/ have a cr@ppy amp, or has anyone else experienced this with the Painkiller?
