As a freelance percussionist, it is often difficult to find a 32" drum that you can move yourself.  Often, they are large, cumbersome instruments that don't fit through most standard doors.  I found a solution that works well for me in getting this 32" Machine model.  It's a copper drum, with legs that collapse inside the drum, so it can be carried easier, and can be turned on it's side to navigate through narrow doorways.  This drum has a hand-crank tuning mechanism and also fitted with a Ludwig standard hoop tuning gauge.  The drum is completely in round, and produces a very clear and resonant sound, and gets great low E's and D's.
