I just ordered a set of six GraphTech piezzo saddles from Stewart MacDonald guitar shop supply. I've been wanting a set of these for years as I'm tired of lugging an acoustic/electric around to every gig for just two songs, and I put the GraphTech saddles on all of my guitars.
So I finally bit the bullet and ordred one. I also ordered the "Quick Switch" where you can switch a mono signal from magnetic pickups, to both, to just the piezzo. Didn't order the preamp assembly with stereo jack for splitting the signal out. I intend to use just one tube amp to amplify the both signals. I hope I don't need to order that preamp to make it work. The website says nothing about needing to have that installed. Anyone every done this mod? ***UPDATE*** Just called StewMac and they said I DO need this preamp. Which sucks because that's a lot of extra crap to shove into the electronics cavity (not to mention $80 more). Oh well... I told him to add it to the order. Might as well go for it.
Also, I'm trying to decide wich guitar to put them on. I'm leaning towards my Godin SD because I've had it forever and will likely never sell it (it's a great-playing guitar that just doesn't command a decent resale value). Other options are the G&L Legacy strat or one of my two ESP Hybrids. The Hybrids have a mahogany body and neck. Whereas the Godin has a maple body and neck and the G&L is swamp ash with a maple neck. Dunno if one of those guitars is better suited than another for the piezzo acoustic sound.
