anyone used a Bartolini NTMB?

[Bob Hoover Ross]

I'm thinking of installing a Bartolini NTMB preamp/EQ (aka HR-3.4/918) in my still-under-construction Warmoth 5-string fretless bass, just wondering if anyone has first-hand experience installing or using these electronics?

I would be using this with a Bartolini MV52CBJD quad-coil humbucker, wired up so that the front & rear coil pairs will be treated as separate neck and bridge pickups.

Any tales of woe, or success stories, or things to look out for when installing, etc?

Thanks.
