The instrument is the 9 tones Halo Pygmy made by Kyle Cox and Jim Dusin of Pantheon Steel, LLC, Farmington, MO, USA. SCALE (C) F G Ab C Eb F G Bb follow the link to see the video recording https://youtu.be/GmuhKqKUMiY Instruments have to be played. I have decided to let go one of my faithful companion of travel and adventures. I have too many instruments and I can't stand to see them on the shelves unplayed. So I have decided to sell my Halo Pygmy (C) (absolutely mesmerizing bass; one of the lowest pitch made by Pantheon Steel) in perfect tuning condition. The halo includes two metal protective shells and a very strong flying case. If you are interested write me to talk. I am looking for someone who wants to play it and enjoy it, Honestly, for the price Id like to get what I paid to Kyle cox, Halo maker I paid 2300 (soft bag included) euro plus 150 for the protective shells and 300 for the instrument flying case costed...so it is 2750,,,but I am open to discuss if u r really interested, is a an amazing instrument in perfect condition.
