Hi folks! I ordered and received a Kala U-Bass SUB Solidbody today, bought from an evilBay listing. It was listed as a B-stock but I have looked it over from headstock to body, front & back, and I cannot see marks of any types. I plugged it in & it sounds very good. I also own a DeArmond Ashbory. These 2 seem to compliment each other very well. My U-Bass SUB is fretted & the Ashbory is fretless. One quick comparison I noticed immediately is the Kala strings feel stronger than those used with the Ashbory. From various threads & other online suggestions, I always loosen the strings of my Ashbory when I'm finished practicing, to save the strings. I do not feel the same using the Kala strings. Unless someone here mentions that I should be down tuning as well. Since I also own an Ashbory, here's a picture of my Ashbory and Kala U-Bass SUB Solidbody side-by-side.
