"Excellent guide and resource for anyone starting out on the Bass Guitar"

— Frank Lawley

“I first heard Greg killing it in the West End show ‘Jersey Boys,’ on bass and background vocals.  We’ve since played on many of the same shows and projects. 

Greg is a strong and versatile player and, going through this book and his video lessons, he shows himself to be a great teacher: clear and concise explanations of the fundamentals of music which will help all players from absolute beginners to more advanced self taught players who maybe didn’t go through formal training, and therefore have gaps in their knowledge."

— Michael Mondesir (Billy Cobham, Jeff Beck, John McLaughlin, Pee Wee Ellis, Royal Academy of Music)
