      "description": "Handcrafted double bass by Holger Krupke with powerful low-end response, warm tone and impressive musical presence.",
      "full_description": "A great double bass does more than keep rhythm. It carries the entire music.   The Double Bass 20950 by Holger Krupke does exactly that with remarkable calmness and presence.   This handcrafted instrument combines traditional double bass craftsmanship with a tonal character full of warmth, depth and dynamics. From the very first notes, it becomes clear that this is not simply about volume \u2014 it is about creating a real musical foundation.  The lower register develops a powerful and projecting tone with plenty of substance, while the response remains open and highly controllable. That balance is exactly what makes premium double basses so special: strength combined with musical flexibility.   This double bass doesn\u2019t only respond to force. It responds to feeling.   Whether bowed or plucked, the Double Bass 20950 creates remarkable tonal openness and a direct connection between player and instrument. Soft passages remain warm and detailed, while stronger playing develops impressive depth and projection.  Especially in ensemble and orchestral settings, it creates the kind of sound that holds music together without overpowering it. At the same time, it offers enough personality for solo passages and expressive playing.  For ambitious bassists. For demanding musicians. For people who don\u2019t just want to accompany music. But carry it.   Deep. Honest. Real.   Handcrafted by Holger Krupke. Traditional German double bass craftsmanship.",
      "additional_text": "Handcrafted double bass by Holger Krupke \n Warm, deep and projecting tonal character \n Powerful bass response with wide dynamics \n Excellent control and direct response \n Suitable for bowed and pizzicato playing \n Ideal for ensemble, orchestra and solo performance \n Traditional craftsmanship \n Designed for ambitious and advanced musicians \n Made in Germany",
