First song, i went to was…A thousand Kisses deep by Leonard Cohen, this singer has to have the best thickest voice. My settings on the ZX2 was in the STUDIO setting, (it’s like an EQ setting to mimic the singer as if he’s in a studio recording live) with the EQ bass at number 5 from 10 being the highest, it’s an EQ preset.
