1. John Mayer has played NOVAX guitars, which feature Bartolini pickups and fanned frets.
The technology behind the fanned fret design "makes sense" but I'm unsure if it is all that noticeable.

This Zachary guy is a Hilarious read if you want a chuckle. He's considered a radical in guitar circles, much like Ed Roman was. I bought some sets of strings from him, and I could tell a little difference in tension, but not really tone. This guys also claims the ONLY guitar you can put 9's on is a tele.
I prefer 10's, and he also has a 10+ set. they are alright. I just can't take the website seriously. Hours of entertainment here.

http://www.daddario.com/DADProductDetail.P...52-cd30c0238f663. Now this one I LOVE and am not kidding... the EZ Peg. It is brass acoustic pegs, milled to where the string can go through the peg. It takes a lot of guess work out of it for beginners, and the way it works allows for less wear on your bridge. It does brighten up the tone a but, add some lovely vibrations to the body, and I believe it sustains longer as well. A cheap and reversible upgrade!

Hellatone takes a celestion Vintage 30 and "breaks them in" for hours so you don't have to. Is this really necessary, or it just a gimick? I know someone on this forum has had to use these before, and am interested in your thoughts on it.
http://www.avatarspeakers.com/hellatone.htm5. This last one, I'm not sure about
Tonerite is something you plug in and hook onto your stings, the vibrations after a few days "simulate playing" and open up the guitar to sound more open and better... as if it had been playing for years. I see the science behind this, and it makes sense to a point, but I"m not sure. I'd like to chip in on one, and maybe we could borrow it for a few weeks to see if it is legit?
