Used as a standalone

I used this system on an enclosed semi-hollow T-style guitar with no controls or other pickups, just plug and play. To my ears, you're best off running the system through a dedicated acoustic amp. The subtleties, nuances and dynamics of a big resonant acoustic guitar are all there, and responds very well to finger picking, without having to lug around something the size of a tea chest. Yes it's not a real acoustic, but then the Rosewood I used wasn't a real Rosewood and that didn't harm the sound in any way either.

Preamp for Teles

Have built 2 teles using ghost saddles, preamp and quick switch. I like that I can adjust the gain of the preamp to match my pickup volume. Preamp is really small but my guitars were semi hollow to allow easy installation.

Built 2 teles with ghost saddles, preamp and quick switch. Bodies were semi hollow to make installation easy. Band members like that I can switch from acoustic to magnetic pickups at the flick of a switch. Recommend battery box be used

I love these things

I have installed a number of these systems with the Ghost saddles and TOM bridges and they are rock solid and beautiful sounding. I have put them in everything from Strats and Tele's to Custom Shop 335's and a Gibson Johnny A (the Johnny A sounded increadible, it's a fully hollow guitar but plays like a solid body. Not sure why the one guy is getting white noise, I have never had this issue and some of the systems I have in are used by touring musicians who get great compliments on the sound. You do need to be careful with the grounding and I suggest using a good quality acoustic amp for the piezo side.

Great sound!

The graphtech piezo system will give you great acoustic sound. Very clean, crisp and bright. Great for guitar players who primarily play electric but might need an acoustic tone for a few songs. You can go from your regular magnetic pickup sound to acoustic with a flip of a switch.

For those of you who have never used a piezo system before don't expect it to sound 'just like an acoustic guitar' This sound will not have the depth of a real acoustic. It sounds more like an electro acoustic guitar but yet even different from that. I feel the piezo sounds best running direct to a mixer rather than an amp. This is also a great sound for studio, you can get it to sound very close to a real acoustic by tweaking the tone knob (if you install one) and using some EQ (I use a RC booster for this)

However I must also mention this piezo system adds a white noise to your signal that's always running in the back ground and is boosted even more when you play through a distorted setting. It won't go away no matter what you try, even if your piezo volume is down to zero.
