I was reading the information about the Gold Tone ME-Bass, which is the solid body version of their Micro Bass. Their web page for it mentions that they have collaborated with LaBella to create a flatwound string called "MBLS MicroBass LaBella Flat Wound Strings". I would like to know if these are metal core or synthetic core strings. I used to own a hollow body microbass, but I sold it because I really didn't like the polymer strings or the synthetic core roundwound strings. I liked playing around with such an ultra-short scale bass though. I think I would like playing one that had metal core strings though. Does anyone know if the MLBS flatwound strings have metal cores?
