So once I realized I had ordered the wrong gauge of Corellis, I decided to put on some old strings (a mixed set) from the stockpile of old strings I have. I've had the following: Obligatos Heliocores Spirocore Weichs La Bella tapewound mystery set that came with the bass I *think* this is all - though I might be missing one set (darn brain fog). Anyway, I put these strings on my bass: E - ball end has green winding with yellow detail A - same as above D - read and black ball end, red winding on peg end G - I know what this one is - the Weich If someone could help me identify which the other three are, it would be much appreciated. Obviously, I am not using any LaBellas! This mixed set is sounding really good to me...a bit heavier overall than the Weich set, so I need to adjust to 'em though! thanks!
