I bought the book after more than two years it was issued and I heard about it.
My knowledges on in reeds adjustment were gained from the "Red Book", my instructors directions, web articles ( including Chris Apps website ) and YOUTUBE video and my own experience. I thought what else could be the news. But incounting on the reed's manipulation problem again and again I decided to read it as a last resort. As soon as I got the manual I read it through with great interest and I found information that was important and helpful to me. As a result I got more accurate and patient in the reed's manipulation. I recommend it to GHB enthusiasts, especially the remoted ones, to make their practice comfortable and their life easier. Thanx to the author. Alex.
