Glad you fancy headless. Straight string pull, no winding around tuning posts. That said Rob's basses are just as good either way. I have both but would choose headless. As far as neck-thru or bolt-on are concerned; neck-thru as stated earlier will give you a more sparkly tone, slightly more top end. Bolt-on will give a slightly warmer tone. The bolt-on is no less of a bass than a neck-thru except neck-thrus cost a lot more. Neck=thrus come with a standard polyurithane finnish while bolt-ons have a natural satin finnish. Either can be selected as a custom order. However, a bolt-on with polyurethane finnish will cost much the same as a neck-thru. I chose bolt-on for my fretless S2. Just a beautiful, full warm tone with Flats on it.
Standard fingerboard is phenolic but you can ask for a wooden board to be fitted. Phenolic will give you a nice bright clear tone, what Status is known for.
Rob now does pickups that can have switches to engage single coils. That gives you even more choice for tone.
Confused. Keep going and you might just be.
