well, i've posted this in here because it is a question about frets. i didn't own a fretless bass until i made one for me, its build is posted here if you are interested look for pine neck. well my question is: are frets related to the sound of slap? i ask that question because when i slap my fretless it doesn't sound the same specially when i pull off strings. i have another question, if i make a soft curve in the fret board in a way that since 12th fret to 22 or 24 is a little bit (just a little bit) slimmer thna the rest of the fretboard it wil be better to avoid fretting after 12th fret? thanks a lot.
