Man, this is great stuff, guys! Thank you. I'm sure alot of folks are thinking, "just install a Ghost or Fishman" but in my experience it is a better acoustic sound if the instrument was designed to have those properties!
I'm curious of any that I can find on the shelf at say GC or SA.
The singer in my band has been experimenting with his new Power Tele. It has its limits but provides a relatively average acoustic sound. The big problem we've encountered is the string gauge compared to a real acoustic. The guitar can't really be aggressively strummed like a real acoustic, the strings really need to be very heavy. We tried heavy strings, it was better but not like the real thing. Also, make sure the DI your acoustic cable goes into has a ground lift.
It sounds kinda like all piezos sound...not quite acoustic
...but it's a Fishman bridge (though some are Fender branded Fishmans).
The cool thing though, is they have a stereo cord that splits to two 1/4" mono cables so you can feed the "acoustic" and magnetic signals to different places.
I was running the Piezo to an L.R. Baggs Para D.I., then into a solid state amp (or the P.A.), while the magnetic pups went to a tube amp.
With a normal guitar cord, both signals mix to mono...I got pretty good results using the Piezo blended with the neck/middle out-of phase, which gave the piezo a little more body in the mids.
Nothing replaces a miked acoustic...
@the fella talking about thicker strings: I agree. They would help...I compromised by using a hybrid set (009-46 I gotta have my bends!), strumming up on the neck and using a thin pick on strummy songs. Not perfect, but it all helped! (Plus the Para D.I. box so you can dial it in a bit.)
A wide range of Carvin's line either comes standard with piezo bridges or can have them installed as original equipment during the build. Generally it's a $100 option on the electric guitars that don't already have them. Carvin also has a wide range of piezo-equipped guitars that additionally have piezo bridges and MIDI synth controls (in addition to the "acoustic" type option).
There are also the Brian Moore iGuitars (some built custom in the US, some build in Korea), including some that have USB output for direct recording and some that have MIDI output). http://www.iguitar.com
There's little difference between a guitar that has the piezos built in and one that's been converted (other than the extra hole that has to be run from the bridge into the control cavity); certainly not a lot of difference sound-wise. Check Graphtech's site for Ghost saddles and bridges and preamp kits.
