After spending hundreds of euro in "A" double bass strings, finishing all the supplies Thomann had of their brands and sets, I finally found the string adapt to my whamola. I popped so many strings in the past months, money straight into the bin, trying to find the right elasticity to handle such stress as a whamola produces. This string is surviving since January (writing in end-July). Great quality, nice colour next to the dark wood of my instrument. I wonder if there is even a brighter string out there. Just got a whamola? Get this string!
