3-Note Exercise Book: Garklein Recorder (The Big Print Recorder Method) Paperback – Large Print, July 22, 2013

This book is on the low quality side (blurry big letters, basic font, decent print), however that doesn't stop it from being simple to follow! Already a very useful method for my garklein (the only one that I could find out there) because of the step by step guide. I would definitely recommend to others that can't seem to find a method for the garklein. :-)
