I ran across this video the other day, and imo, it is an awesome example of how the Tone Zone sounds when the "zone" has been found (aka not muddy!)
Sounds awesome!

Thanks for posting that video. I almost got rid of a tone zone but after seeing (and hearing) that video, I'm keeping it now. 1 karma
Update on my Tone Zone experience.
I installed my black and creme TZ in my homemade Malmsteen strat (with an Air Norton S in the neck and Fast Track 1 middle). At first I was getting a fairly good tone, but it was kind of "buzzy" to my ears. I adjusted it up and down 1/4 turn each way and still heard the same "buzzy" tone that I really didn't care for. I was about to pull it out and put in a spare Norton in it's place when I decided to keep working with it, I lowered the pickup as low as I dared, then raised it a 1/4 turn at a time, letting it set over night so I can have fresh ears to make sure it was going in the right direction (tone wise). About a week and half went by with me adjusting the Tone Zone 1/4 turn at a time and then I entered the "Zone". It was one 1/4 turn that suddenly brought the TZ to life. It was like a cloak was placed over the amp and was suddenly removed. Everything sounded alive, the "buzzy" tone that I heard in the beginning was gone and was replaced with a very clean (?) type of overdriven/distortion. All the notes of any chord were very pronounced and huge sounding. Leads seem to be very FAT and Round in all the right places. There are some harmonics, but they are nothing like the Norton or Fred, but they are there. I look back at this and think that I almost pulled this out of my strat and was going to replace it with a Norton. I can usually dial a Norton in a couple of hours, but the TZ took me a week and half to find the spot. Once you are in the spot, you will have roughly 1/8 of a turn to play with but you have to find the spot with the TZ first.
I have been in love with the Norton for quite some time now, and I'm starting to have some of those same feelings for the Tone Zone (I need more guitars!!) It's a keeper!
