I have been a dyed-in-the-wool Spiro guy for years....tried the Blues, Obligato...good strings, but nothing, in my New-England-bred-tiny mind, equalled Spiros. Then....just today, I got a brand-spankin' new bass while here in China. A handmade, solid maple back and ribs, Canadian spruce top bass. A flipping CANNON of a jazz bass, with sustain and growl FOR DAYS!! Had Helicore hybrids on it...an ok string, but kind of dead-sounding. I put on some Helicore Pizz strings. W-O-W!!!!! KILLING! I had NO idea how growly and big these strings sound! Anyone else here playing these strings, and like/love them? I am bowled over about how good these sound on my new bass! Perhaps when I get back to the US, I'll revert back to my old ways and try some Spiro Weichs on it, but for now, this Ex-Pat is one very happy camper!! Thoughts?
