I'm planning on building my first bass. I want to use a single pickup to keep costs down. Also, I play blues and 50s - 60s rock, so a lot of tonal options isn't essential. However, I don't know the tonal differences between the P-Bass unsplit single coil (4-slug type, not J-Bass type) and the P-Bass split single coil. Please enlighten me. Also, does anyone have an opinion (tonal, not aesthetic) on an all-alder body vs. maple-topped alder? (the bass will have a maple neck & rosewood FB) Thanks!
