To add, quality in budget instruments might've went up, but "you get what you pay for" definitely comes to mind. Yea, you'll get a "maple neck" but are you getting a strong quality maple or a flimsy piece of maple with a truss rod routed into it? Yes you'll get a basswood/ swamp ash body, but again, what's it's quality? I remember before Squier upped their game many people would go "it came put together but one bump or drop and I was already putting chips in it". Cheaper basses are made partially with cheaper selections of wood. Meanwhile I keep referencing my Carvin but you get not only well aged wood, you get graphite reinforcement to prevent warping etc. And that's around the 8x marker. Some players can polish a turd, not forgetting that out of the box intonation/ action were issues that you saw Scott fix. As far as the whole bag of "it sounded great because of the player"... Well, it couldn't be that the manufacturer realized a jazz bass doesn't equal to a jazz bass unless it meets some fundamentals of the sound?
The most evident sound difference should come down to the coils. Single coil vs dual coil! It's not difficult!
This video I think makes it dead simple in comparison with Scott's. You don't even need a 2nd bass to demonstrate it.
Jazz pups are flat, high mid heavy (trebly, even), "transparent" sound. The MM? Lots of low-mid honk, bassy, highs are present but rolled off in comparison to the jazz pickups.
There's plenty of "the tone is in the player" content online but I think the scope of that statement is useless without examining the lenses it's viewed under.
Lol whatever man, just make sure you imagine having all the deluxe controls that the Sadowsky comes with while reviewing the Ammoon. Totally will pay off.
