I play the Mellow Tone chromatic harmonica by Hohner, two Paddy Richter tuned Suzuki pro-master harmonicas in G and D (the latter with valves), a Golden Melody in A, a Blues Harp in G, a couple of Lee Oskars in country tuning and natural minor tuning and my favourite: a Suzuki Manji in C
Edit: All the harmonicas mentioned except the first are diationics.
