I finished this kit at about 4:30 this morning. I think that between this and my first project which was a Dan Armstrong Orange Squeezer, I am turning into a F'n geek..... No noise, does twang to no end, chime, swirl everything- a very rich sound. Oh, and I used to dislike, that "swirl" term until I built this thing. Now I understand. It gives a nice tube-like sound at higher gain settings. It won't turn your amp into a Vox, but you can pull up along side one with this. I think the Celestion Blue has a significant contribution to that sound, and I am using an Emi Rajin Cajun and Copperhead right now. I highly recommend this kit for only $70. It may require some patience though, go slow. I did mine in 2 hour increments here and there. You should have a multimeter, "Helping Hands", and I recommend 24 guage solid core "rainbow" wire - all from Radio Shack. All of this will come in handy for your next project.
