I play a 1978 4001 fretless Rick. I like the sound of roundwound (I used Roto-sound roundwounds and gouged my neck) strings before using some Dean Markley half-round strings with a 107 E-string which they do not make anymore. Do any fretless players have a good string for me to use, I like the heavier strings (hard to find thicker than 105 E-string) and love the sound of round wounds although i can't use them on my bass. Any suggestions would be greatly appreciated. From a Stanley, Jaco, Billy and Geddy fan.
