My hunch is they have a negative effect on the sound. Wouldn't a full signal to a good head be better controlled by the head?

It's a lot of work for zero gain IMO. You'll have to remove the pre-amp and some pickups are powered as well.
There are some that do it. However you will see a minimal change if any at all. with the tone at 100% your signal doesn't actually travel through much so it really doesn't have the ability make much changes.
Also I think the tone control gives you a sound control that an amp really doesn't. You can mimic the sound of a rolled off tone with an amp but its not quite the same. I think a better pot and maybe a new cap (maybe try different values) would help more than removing it.

I bought my Precision at a significant discount because the pickup was DOA at Guitar Center. Not wanting to mess with too much soldering, and wanting a nice celluloid tortoise pickguard, I ordered a custom pickguard from Warmoth with no holes for the tone or volume knobs and wired a replacement pickup straight to the output jack.
It works great for me, I never use the knobs on a passive bass anyway. A mute switch on the amp or an inline tuner takes care of the on/off function I would use the volume knob for... and I think it looks nice. It's a bit brighter than it would be with the pots wired in and turned up all the way, which is fine.

Will achieve exactly nothing compared to leaving the tone knob all the way up, in the case of just about every bass. Removal of the remaining 250k-to-ground might imperceptibly change the resonant frequencies, but you'll get more tonal variation by choosing a different patch cable. A lot more.
What kind of amp is that?![]()
i'll repeat what I said earlier: a lot of work for zero gain. With the tone control removed the difference will be almost imperceptible. Easiest way to check is to unsolder one end of the tone cap. That will effectively delete the pot from the equation.
I've done this on both one bass and one (treble?) guitar. This was just some experimenting I did in the course of repairs. In both cases it made the sound brighter, in the case of the bass it seemed to make the signal louder as well.
Not worth it though, I think. Volume and tone knobs on bass are necessary for switching between fingers and pick, in my opinion.
