There is no good hybrid string. They all stink. I was the guy that first brought Obligatos to TalkBass. At the outset, they seemed to do the job both ways. I had Obligatos on my precious orchestra bass and on Old 87, my 1925 American Standard. I had a symphony concert where the cello soloist played a Strad - the "Prince Gursky". (And don't tell Branstetter it has been altered, as have most Strads.) I felt a moral obligation to use guts, so I put on my Olivs. Glorious sound. Next night was a big band gig. I used Old 87 with the Obligatos. Big but foggy tone, and that annoying rolling of the string under pizz pressure. So the other night I put on Spirocore solo strings tuned down. Presto! Clear intonation, powerful jazz pizz sound. The moral: Stop looking for one string to do it all. Buy an electric drill from Black & Decker - reversible, cordless, variable speed. Then a wooden bit made for bass tuner keys. (Got mine from Gage.) You can change a set of strings in a few minutes, effortlessly. Use the right string for the job. You'll be happier with the result.
