how do I recreate the magic?

[smart51]

I've made several basses now, of all different types. They're all good in their own way but one stands out. The first one. The tone is by far the best bass I've owned. I have no idea why it is so good, so I don't know how I can recreate it.

The tone is bright for sure, but has some deep bottom end, and the B and E strings growl in the lower notes. It only has one pickup and tone control, but it is versatile in tone too.

In construction, it has a single piece black limba through neck with a wenge fretboard. The wings are wenge too, separated from the neck by a strip of maple. The neck is chunky. Very chunky, with an offset V profile that is shaped to match my left hand. Despite being thick, it is very comfortable to play. It is a headless instrument with a brass headpiece and matching brass nut. Being headless, the bridge is brass too.

What is it from that recipe that makes its tone?

The stiffness of the lumber choices, the windings in the pickup and the placement of the pickup.
I'd say those are the main factors as a start.

The main reason for the improved bottom end is the overall stiffness of the neck and the neck/body joint. By luck or design, you got the stiffness in the right range. Clarity of the deep lows, without losing the warmth of the mids. You can hear the fundamentals and the growls. If the neck structure is too soft, the deep lows will be mushy and wooly, poor definition. Too stiff, and the bass sounds cold and sterile. You got it right.

The pickup plays a part too. You need a pickup that can detect deep low clarity. Many commercial aftermarket pickups are made to deliberately make the lows mushy. To warm up the sound of Fenders. You need a clear Hi-Fi style pickup.

The other part of that sound comes from good solid metal hardware, connecting the strings tightly to the wood. Careful detail in how the hardware is mounted brings out clarity at the high end. You don't necessarily need a ton of brass, but you need to pay attention to how securely the hardware is attached to the wood frame.

Those are the factors that we practice to bring out the bass sound that you describe.
