I recently part-exchanged my MK sig standard for an SC deluxe. Apart from a few little cosmetic differences (purpleheart neck laminates, laminates on the back of the body) I was expecting the SC deluxe to be pretty much the same bass as my MK standard. Having now played it in a gig situation, I have to say that the SC deluxe is in a whole different league. I realise now that those differences between the standard and the deluxe (esp. the purpleheart in the neck) are a whole lot more than just 'cosmetic' - to me, this bass sounds deeper, warmer and more focussed, yet still keeping the sparkling highs that I was used to.
But I have a question: on close inspection of the neck of the SC deluxe, I see that there is a thin accent of some other wood between the maple/purpleheart and the ebony fretboard - don't think it's more purpleheart - could be mahogany. My old MK standard didn't have this - I knew about the other 'cosmetic' differences between the standard and the deluxe, but have never seen or heard about this before. Is this extra neck accent normal on sig deluxe basses? Does it contribute to a difference in tone or is it purely aesthetic?
