Hey, i'm making a 6 string fretless in woodwork this year and was just wondering if i could get some opinions on this.. Walnut back, mahogany core, coco bolo top, ebony fingerboard and maybe wenge neck? (I'm not too sure on the neck wood). I don't know if it'l be bolt on or set/neck through just yet as i have to see if i can get help/equipment usage from a friend. I want something kinda deep and thumpy with nice attack (Think Claypools rainbow bass), yet can be smooth enough to get a real nice fretless tone. I'l be using EMG electronics most likely (Dual coil and a P or J). So what do you think of that? Should i use something else other than coco bolo? Or something other than mahogany? Thanks.
