Bart NTMB Mid control trouble

Zombbg4 · #1 12-17-2008, 07:54 PM

I've got a bartolini NTMB preamp which has the frequency selecting mid control, pretty cool. Only its not working...and never worked, It was in the bass when I got it. Its a push/pull pot-push for low mids pull for high mid and when I pull it out it doesnt change at all.

Any help? I'm totally clueless and craving high mid control!

May be the switch have some problem, or the wiring is wrong........ If you know soldering, you can DIY, otherwise, you should go to pro.....

Goodluck,

Just verifying that you've got the mid level at an extreme when you test. Sorry if that's an obvious question. I do IT work and sometimes the obvious gets overlooked.

Yea I boost it all the way, pull it up and no change. Roll it off, pull it out, the same. Tried it all with the conclusion that its the same, unless the 2nd frequency is like 250.5 compared to 250.

What I'm looking for is an answer like; A connects to B, when you pull D connects to C ect...

Something like that by someone who knows how to hook one of these up/how they work.
