Unsure of the origins of these. Just taken them off a bass I got in a trade. No branding on them at all.
Comes with a bag of 6-7 black strings also (the ones that were on felt around 105-45. My guess is they are DR Black Beauties but that's cause I don't know any other black coated bass string brands.
Hi mass bridge, black metal knobs and black string tree.
Included are all the black screws also.
Price includes UK postage.
Cheers.
