ive been through 'em all. had spirocores on my carved eastman for a while, but i love playing arco, even though most (90%) of my jobs are pizz. The spiros gave me too scratchy a tone even after a while. The bass has darkened considerably since then, but helicores still speak so muc more beautifully on it for pizz AND arco; and it's LOUD. all that being said, it is the best sound i've found on MY bass. I've still got the mittel E spiro on it due to its depth and definition.
by mistake and my lack of looking up the color charts and inheriting half a set of helicores from a buddy, i put a medium D helicore on it at G. the tension is a liiiittle funny and didnt think anything of it at first except it was a little thick (thought it was a heavy). boy does it sing and sound so full! got a medium D on both the G and D now, thinking of hittin up a heavy G that has 0.5lb less tension than a medium D...[Invalid or Expired Link Removed]. hoping it feels a little smaller than the D on there now. anyone have any experience mixing gauges of strings like that? (ie two Ds of differing tensions?)
oh, yes helicores sound great for doubling, and cheap! pretty important these days and seems like theyre a great starting point to get a feel for which direction you want to take your string quest.
PS ive got an evah E and A that i didnt like that were on my bass for barely a week. anyone interested in a trade or $$?
