Well crap, I went and played a KOT and POT yesterday and love them. Problem is they are way out of my price range so looking for alternatives. My understanding is that they are a modified BB so here are the ones I know of: Wilson Effects Black Tooth Grin CMATMODS Butah JHS Morning Glory - Same price as POT I would like to get in as close to $100 as possible. Also, do these sound good through a SFPR? I demo'd them through a Pritchard Satori.
