Hammond SK1-73

Portable Keyboard, 73-note


Hammond SK1-73

The SK series stage keyboards at the most revolutionary Hammonds yet. These ultralight instruments provide the essential keyboard sounds required to play any show in any style, including a genuine and vintage-perfect Hammond organ in compact packages with all the features expected in a vintage B-3. Many keyboardists have accepted the 73 note keyboard as the Standard, due to the need to play piano parts comfortably when you're an Organist or Synth player. Sometimes 61 keys aren't enough, but the 88-note board is too much-73 is "just right." In any case, to have this much firepower in an instrument that is less than 10 kilograms is liberating and inspiring in and of itself. The HAMMOND SK 1-73 is "just right" in many more ways.
