Review on

"I came across the Bass Matrix on YouTube and although I've been playing electric bass for 30 years and play from both sheet music and tabs, there are lots of new rhythmic ideas and explanations at the start, which are supplemented by YouTube links. Absolutely recommended to buy!!!"

Customer rating on AMAZON

"Beginners, intermediate players, professionals – everyone gets their money's worth. You don't even have to be able to read sheet music, as Rehm has devised a new notation system specifically for this book, which is intuitive and therefore quick to adapt to."
