I used to own a Yuka (singlecut version) by Grossman for a few months, i have to say this bass was everything u can expect from a well built instrument, light, well balanced, really "singing" and versatile... Neck on mine was more "P" shaped than i usually like but it was definitely a NICE 5 string...
Good luck with sale
ps : how is the fretboard? (mine was radiused on top and getting flatter near the body, but it might have been a special feature...)
