“It's one of the best, if not the best, instuctional system out there. I've got it, and I've been chewin' my way thru it for a year now; there's stuff in there that takes years to perfect, and there's simple things that I hadn't learned in 35 years of playin'. It's great for fundamentals and upper level stuff, and well worth the $$$.”

“The Portnoy Masterclass is the most comprehensive blues harp lesson set I have heard. True, it will take you years to master, but without the detailed explanations and sound bite examples you would never figure out a lot of the techniques on your own. Highly recommended.”

“Jerry's approach to the harmonica is extremely methodical; breaking down each and every note and working each technique to perfection. To say that Jerry is a perfectionist is an understatement…I would strongly recommend that any of you reading this who are currently playing the harmonica or would like to learn how to play go to this page on Jerry's site: http://www.harpmaster.com and purchase his 3-CD instructional seminar. It is without a doubt the best instructional CD on the harmonica that you will find.”
- Bob Stannard

“I've known Jerry personally since he was with Muddy since the 70's, and the set is well worth it because you'll be learning from the REAL DEAL in blues harmonica and one of the best, and Muddy Waters signature was having one of the very BEST blues harmonica players around in his band and the roster of harp players is more like the who's who of the very best in the business. Get it and don't even think about it!!!!”

"Summarizing: Portnoy's course is the best and most comprehensive I ever saw. It treats almost every technique in an understandable and stimulating way. Level: beginner to advanced. Absolutely worth the money!"
