After years of dreaming about it, I finally purchased an upright. Got a great deal ( I think) on a Knilling. I'm trying to stay with my local mom and pop store for a pickup. The only one they recomended was a polytone. They admitted have very little knowledge on the subject however. Anyone have any thoughts on the subject? I'd be using an SWR Super Redhead for an amp. Thanks for any and all help!!!
