Caused by listening to bad recordings from the eighties. A contagious disease that can be aggravated by one's peers.
Just having fun I've got my tweeks too.
Try the Totem Beak if you're interested. I don't know why they work, but they sure do!
They look like Mapleshade products.
I would recommend Walker Valid Points from walkeraudio instead. Cheers,
