This past week I tried some Cobalt Flats on my Ken Taylor signature and got some insteresting tones. I don't know how I did it, but I got a very close sound to a string bass. While I can't duplicate that sound with those strings on my Yamaha TRBX605 due to the pickups/electronics differences, in general the Yamaha is too eerily similar to the Sandberg... So the Sandberg SS strings went back on!When I had a Basic VM5, the strings I liked best were Cobalt Flats.
