I got it installed.....it sounds really cool. In normal mode you can have your guitar sustain the original note (clean or dirty) forever. You can also flip a switch and have it go into harmonic mode where it sounds like a pinch or artificial harmonic every time as the note rings out when you hit it normally. You can also hit a blend switch where it will do both at the same time. At any time you can adjust the intensity for just a bit of sustain, which you will barely notice...of full on where it will vibrate the strings so hard it tickles your fingers.....much like the vibrator your girlfriend uses after you roll over and go to sleep.
A good example of this device is on VH3 when Ed plays "year to the day"...he has it cranked the entire song.
Here is what my Jackson Dinky looked like before the mod.
Here is what the kit looks like...a circuit board, a bridge PUP and a neck PUP/sensor. They are mounted on that plastic template just for shipping.
And here is the final result....I still need to calibrate it and do some testing. I might put the original PUP back on, because this bridge humbucker is a bit light. It should work with any humbucker. The front driver works like a regular PUP when teh thing is turned off. I had to modify a neck humbucker to fill the slot and some minor routing to get everything to fit. Right now I have the battery inside the cavity, but I am going to go and mount the external battery case now (router needed for that mod).
It's a fun toy if you have an extra $200 lying around the house. It makes it seem like your amp is dimed out at extremely low volumes. I've only used it for 5 minites, but so far I love the thing. I can see why Ed likes them so much.
