can anyone recommend a good string for a fretless jazz bass, similar to dr sunbeams? the sunbeams have gotten rave reviews and seem to be the sound i'm going for (mellow, growly, good midrange), but the supposed low tension is throwing me off. i like to dig in a bit, at times. what could compare to the sunbeams with a little more tension? fender 7250s? dr nickel lo-riders? dean markley nickels? thanks!!
