The first three models were tweaked into their current form by Stefon Harris to make a series of soft, medium hard, and hard, that could also be used in a graduated set. Albright mallets also feature substantially larger heads than other models that Malletech offers.
“I just recorded with Diana Krall. These new Albrights are amazing live and in the studio. I couldn’t have predicted the dramatic effect that a mallet has on one’s ability to make music. Recently, I’ve had some of my most inspired performances and that’s clearly related to these mallets!”
