MISTAKES IN THE BOOKS
I bought 3 series of their books and discovered errors in the chords. I contacted the company for a refund and their reply was “ unfortunately you are outside our refund terms but good catch, we will pass this onto our content providers for future printing runs”
I said your company knows there are mistakes in your books and you are knowingly selling them. What about all the people buying right now ?
THEIR RESPONSE - zero !

The books were not delivered. Instead, we received a notice stating that an additional customs duty had to be paid. When we inquired about this a few days later, we were told that the books had already been returned to the United States. We received no response to our email requesting an explanation or some form of compensation. Money lost.

I’ve bought several books and courses. Excellent content.
Customer service is great too. I made a mistake with an order I placed and they worked to make it right for me.

Progressions: Classics Volume 1-3 sind schöne Gitarrenhefte. Allerdings sind diese äußerst gehaltlos. Die selben Akkorde unendlich oft wiederholt. Es gab noch nie ein "Notenheft", welches ich an einem Tag komplett konnte.

My husband ordered a progressions series of 3 books on November 28. It's now Dec 19 and not only have we not received the books, he emailed the company and have not had any reply. We are both beginning to wonder how legit this company is. Maybe it's simply poorly managed. Either way, it's a real problem.
