Blackouts Modular Preamp?

[Artie]

Can anyone clarify if the BMP-1 uses a differential input topology, and therefore, must be used with 4-wire pups?

Thanks all.

You should PM JOLLY he is the biggest Blackouts fan around here I know of

 

[Artie]

Thanks Securb. I'll wait a bit and see if he see's this.

BTW, how do you do the name-as-a-link thang?

I emailed Duncan support. They do indeed, need 4-wire pups.

Just put an @ before the username and you will get a pull-down menu of members. One cool feature of the forum upgrade. I guess it wasn't all bad.

I believe it was confirmed early on that the BMP-1 needs 4-conductor pickups.

Also, don't know if this helps:

...the preamp is intended to act like a humbucker in itself. The signal from one coil comes in out of phase and is inverted when summed, thus cancelling more hum...A single coil wired into one half of the preamp will hum. Also one of the coils is loaded. So pretend one coil has a low value pot on it. It's darker sounding than the other one. Together it makes up the expected sound, but separately only one of the coils (represented by the white wire in our schematic) is "flat" sounding.

EDIT: I see you got your answer straight from the source

Yup. But that info is still helpful. I hadn't seen that before. Thanks.

And thanks Securb for the forum hint.

The BMP-1 is a differential preamp with a lot more going on before the opamp compared to the EMG circuit.

Are these things still available? I would love to mate one up with a pair of EMG HZ3's in a BC Rich.

That's funny. A BC Rich Warlock is what I was thinking of putting mine into. They do still show them on the website.

I transplanted the HZ's from my DXMG. I always thought that if I put them through a pre-amp, then they would sound a lot more like 81's. They are 4 conductor. So what's to lose?

I transplanted the HZ's from my DXMG.

Mine is the Warlock NJ, (Nagaoka, Japan), with the reverse 6-on-side headstock. It has EMG "Selects". Kinda like Duncan Designed. They sound pretty good, but they're 3-wire. Hot & ground, and then a wire to split. I'm still deciding what to do with this one because I'll probably sell it.
