could Blackouts powered externally?

Hey good people

Wondering if any has used the external power supply from EMG to work with blackouts or if there is any other way for the blackouts/preamp to be powered externally?

Cheers
 
Re: could Blackouts powered externally?

I'm thinking yes. I built a phantom power box for my livewire II's and EMG's.

Yes but it will require using a stereo cable from the guitar to the power supply box.

Someone posted a schematic on how to make one awhile back, I'll have to look for it.

I posted a schematic a while ago but I can't find it anymore.

Not to be rude, but why would you want to do this? A battery lasts a long time and is a clean power source. An external power source would be dependent on the electrical wiring of where ever you played. It seems like you're adding factors in that don't need to be there.

It's not an AC/DC converter. Instead it's an external battery pack that makes wiring a guitar with active pickups much simpler.

The wiring on the guitar is simple you just remove the battery harness from the equation and go directly to the jack. In the original diagram they use a stereo jack because it completes the circuit with a mono cord and turns the preamp on/off when plugged/unplugged.

In my diagram I use a stereo cord because I can transmit signal on one side and power on the other without modifying the guitars wiring. The power box just splits the power from the output by reversing the process. There are two grounds so just try an alligator clip to see which works, IIRC I used the middle? I put the jacks and wires in a small Radio Shack box so I can have one phantom power box for multiple guitars. It's much easier to change batteries in the box than dismantle and restring a guitar.

I was using that in the 80s. I used XLR microphone cables to the guitar and had a small box in front of the amp splitting into the 1/4 plug for the amp and the power supply. Main reason was that I didn't want to make an easily accessible battery compartment for my Blazer. I only had top pickguard guitars back in the day.

With my one EMG equipped guitar, I have toyed with the idea of using an external battery pack just to free up space in the control cavity. Cramming two batteries in there for 18 volts leaves me worrying that I am going to eventually push a battery too hard and short or split a connection. Optimally, I would like to upgrade to the X series pickups, but an external battery pack is a cheaper alternative for the short-term.

For me the most expensive part of building the phantom power box was buying the stereo cord. Everything else I had on hand.
