for my future warmoth project bass ... i'm planning to build a swamp ash jazz bass with a flamed koa top. i'v emailed bassculure and they said it was posible to get a pickup(cover) also from flamed koa. (for a MM pickup) what do you think about the looks? or should i just take plastic cover? and what about the sound?? do they sound good? i really like an sound agressive as possible (stingray, flea bass) should i take a bassculture pickup?
