So I just bought the new bass magazine "Guitar world's Bass Guitar". I liked it alot and I saw this huge two page add for something called the perfect pitch. They also have a homepage located at http://www.perfectpitch.com The add seem so unbelievable I can't really think that this is true. So I was wondering if anyone has ever tried this thing before. It feels they are bs'ing us with all the positive things they write. I just want to hear for myself if someone has actually used this and how well it has worked out for them. So have anyone here used perfect pitch and how effective was it?
