i like that modern sustaining pizz sound. definately not the gut thing. i know that guys use the orch strings for pizz for a more traditional gut like sound with less sustain than the spirocore type sound. my problem is that i like that spirocore sound for pizz but i want to work on some bottesini stuff, and i think i'll just need to get the orch strings because any hybrid type string i've used just doesnt cut it. i have obligatos on now, and they sound great pizz and ok arco, but they dont amplify well on that particular bass so i cant really use it on a jazz gig. here's my idea: put the helicore orch strings on for the arco purpose, and use a piezo pickup for jazz thump and blend it with a magnetic pick up to add some sustain. ( i have the necessary equipment) the magnetic pickup i have seems to add sustain to any kind of string i use it with, but it wont work with the obligatos because there's not enough metal content. any comments?
