Super Bass

This bass has a super fat sound. I'm not a professional and only play for home use. But I was very pleasantly surprised by this model. On the one hand, this bass is light and easy to handle, the frets are closer together, it's a short scale, and as I have small hands I can grip it better, I don't cramp up and I'm quicker and more precise with the fingerings.
The communication with Musikhaus Kirstein is flawless, I was again very satisfied, and the delivery was again very fast. So I can only praise both the instrument and the music store and recommend them highly. Gladly again.
Incredible sound

I was very skeptical. Short Scale and very cheap.
So quickly connected and tried. The first sound and I was happy. WOW I could only say.
Much better than my older model of another brand.
The weight is sensationally low. The short neck suits me very well and does not reduce the sound at all.
I had an active bass before. I like this model better. Absolute recommendation from me.

Excellent bass, I knew that it is a shortscale bass, but was surprised how "short" he really is. But despite its short scale length 762 mm, I immediately came to grips with it, for me not too big change from a longscale to a shortscale. I am absolutely thrilled , playing difficult riffs is easier for me because I can implement it better .
So from me a 10+
