The Seydel Blues SESSION STEEL Paddy Richter Harmonica is a blues harmonica with corrosion-free stainless steel reeds, ergonomic covers and plastic comb. The SESSION STEEL is the upgrade to the successful SESSION model with a bold new look and superior technical reliability, excellent playability and a fantastic sound. It's tuned in the Paddy Richter style, which raises the 3 blow by a semitone, making this harp suitable for everything from the blues to Irish jugs.
