Bartolini preamp help

[fruitlabor]

I have a 3 band Bartolini preamp that’s 4 knobs with stacked bass/treble. Can I possibly change that to 2 separate pots and what would I need to do so…All help is greatly appreciated

Which Bart preamp is it?
Why don’t you want a stacked bass treble?

I have a 5 hole bass and I was able to get this at a very reasonable price

A stacked EQ pot for a Bart is two of these put together:

Noble - EQ Pot - 50K EQ - Best Bass Gear

Or any 50k Linear Pot with center detent.

You need to buy new pots. Here you can find out the pot values you need: Wiring Diagrams - Bartolini Pickups & Electronics
The physical dimensions of the pots depend on the type of bass you have: [Invalid or Expired Link Removed]

It’s the NTMB+F preamp

Great preamp depending on what you like. I have one matched with Bart P/J fretless. Wow is all i can say.
Before you go unsoldering things, you could just add a "dummy" switch or knob to the empty hole?

That’s true also

That’s true also

OR...... The one con I have against the NTMB is that there is no passive tone/treble. There are times where I liketo go passive, and I can, but with no tone knob. So that is one option guys with the NTMB do

I wouldn’t change it, get a dummy and turn it every so often and people will think you have 6 knobs lol

The stacked pot basically just has 2 "bodies" on the underside, each wired the way a single pot performing the same function would be. Just get two single pots of the correct style and value then wire them like the corresponding pot on the stack. You'll probably have to extend the leads, I'd leave enough for each single pot to reach the furthest possible hole, then tidy up any excess wire after they are in the correct position.

That’s the plan. I ordered a couple of Noble eq post recommended by mmbongo. Looks like that will work out fine. The dummy is ok for now but I like having separate tone pots anyway. Thank you all…blessings

The bartolini NTMB come in pre wired or module and parts. You can configure it anyway you like but you need the right parts. Bestbassgear.com has all the wiring diagrams and parts.
