I own both Tone Zones and a Nail Bomb.
Let me assure you there is no comparison. Bare Knuckle pickups are at a completely different level than DiMarzio. The depth, clarity, quality of sound is sooooo much better.
You can take the same picture with a cell phone camera or a 30 megapixel digital SLR. Only one of these photos will be good enough to enlarge and publish on a billboard. They both may look the same on a web page however.
Once you get the Nail Bombs installed and play at volume on stage, you will hear the difference in "resolution" my friend. Clips may sound similar on compressed mp3 files on the internet, but that is not IRL....
