Hey folks! I've been a devoted Spirocore user for a little while now. I'm studying primarily jazz and contemporary styles at school, but I also take classical lessons and play in the string orchestra as well as big band. It's no news that Spirocores don't bow particularly well, and even my jazz bass instructor (who has used Spiros almost exclusively for the last 40 years) recommended I make the switch over to Evah Pirazzi since I do such a wide variety of playing. I like the brightness and feel of the Spirocore weichs, however I'd like to try something that bows a little better. My only obstacle is that the pickup I use is a Krivo Magnetic Pickup, which I have been very happy with. I have a Realist attached, but it doesn't get along with my amp very well so I really only use it through a PA. However, with the Krivo being magnetic, it won't accept anything but all-metal strings. I have a set of Zyex's that I liked but can no longer use since they're synthetic core. My question now is will Evah Pirazzis work with a magnetic pickup? I read that they do have a synthetic core but I was wondering if anyone had any experience with the two. If not, what would be some recommendations for a mainly jazz player who also doesn't want to sound like nails on a chalkboard while playing a concerto? Thanks!
