I was able to check out a Swingmaster w/ what I believe were Eurosonics (looked just like them, kinda milky clear nylony, huge E string) at my local bass place (Hamilton-Ashley, Seattle). After all the chatter I wanted to try them arco. I had no problem starting them and they bowed o.k. However, playing pizz and doing a little slide, I could not get a growl out of them. I doubt if they were the lights (as the E string was almost as wide as my pinkie). Anyone know if the lights might be made to growl? Or any suggestions of a nylon string that can be bowed and still have a nice pizz growl?
