Hi. Any advice please. I am using a focusrite 212 interface but would like to upgrade my sound for vocals, so the focusrite Clarett 2 Chanel looks interesting with its air settings and maybe upgraded pre amps, or I am thinking linking up a solid state mic preamp, maybe a Dbx 286s or maybe a Golden age or similar preamp, just looking for a step up in terms of vocal colour or clarity, under £400 , any recommendations? For a country/blues vocalist. Thanks
