Graph Tech Acousti-phonic wiring

[Fat Pete]

I have one of these to hook up - looks like lots of fun. There's a cap included in the wiring kit and on an online wiring diagram that is not shown or mentioned in the paper manual that came with the kit. As shown below it's connected to an auxiliary lead that can be used to power active pickups. My question is: as I'm not using it to power anything and there's nothing to decouple (or whatever it's doing), do I need to connect it?

Online diagram (part):

I know the simple answer is probably just wire it as shown and not worry about it, but I'd prefer not to add unnecessary circuitry - or at least know why it's there.

No, it's just a filter cap, used like the filters in power supplies to flatten out the DC. You're feeding DC from a battery in that circuit so you wouldn't think you'd need it, but a typical 9V battery doesn't have a lotta current sourcing ability so an uneven load could cause voltage fluctuations that a downstream device might be sensitive to. That cap would theoretically prevent that.

Bottom line is, you don't need it. Put it in your Drawer of Misfit Parts where it can dream of future projects.

Put together a $1200 Tele with a spare Cap I have lying around?

I quite like the idea of the Acoustic systems in an Electric guitar. I plan on doing a guitar with one one day...

I put the Acoustiphonic system in my black Jazzmaster. All by itself, it's not worth much. Needs post-processing or it just sounds like a crappy electric guitar. But, it's a better signal for doing that than the magnetic can provide, so it ends up being worthwhile. For the MIDI thing, I put one of those Fishman TriplePlay units on there. Pretty magical. Surprisingly low latency, unlike most analog-to-MIDI converters.

Thanks, but I just installed this one. Not sure if/when I'll need another.

Why are you selling yours?

Thanks Kevin

I keep intending to voice a piezo for electric guitar sounds instead of fauxoustic guitar. Because its a mechanical transducer,it gets really fun a room filling volumes. Sounds like you're playing at stadium levels.

I have a guitar with a piezo in it.  If you want it to sound more acoustic, here are some tips I have learned.

Get a preamp for it.
Dedicate onboard EQ for it (it really needs totally different EQ than mag pups)
Run it through a DI into a FRFR system
If you are modeling and using IRs, get an acoustic IR
If possible, use a wound G

Of these I have the 1st 2. I run mine into my AXE-FX with an acoustic IR.  That gets me 95% of the way there
