There are more than a few here that have both the AMPs as well as the Masterbuilt and I like both. My next purchase will be a dust tube. I think then I can relax and just learn how to best use each one. I know a lot of folks here love their tubes too.
I haven't attempted cheese or fish or any of the main reasons for the cold smoke yet. I only bought the masterbuilt to try on sausage and andouille and lord knows when it'll get cool enough now to do some. Well and it was on one heck of a sale.
There is a thread on here by folks with the masterbuilt cold smokers and I believe if I remember correctly, that most were really happy. That was why I decided to give it a try. I even heard one person say they liked it enough that they were going to attach it to a freezer smoker so as to smoke more fish.
I really have not had a problem, but still learning. I was trying to use the cold smoker as a standard aux. smoke generator for long smokes. What I did see what a beautiful new color added to the meat vice the dark colors of the normal chips (thats a pretty color too, just different!).
I tried it on a turkey, well turkey legs, and I hope I can do it again the same way.
Can you adjust the amount of smoke with the Masterbuilt Cold Smoker, like David Williams asked??? I kicked that over to you, because I have no idea. You gave the political answer, answering everything but the question. That's why I love ya.
BTW: The Amazing Tube Smoker is for pellets---Not Dust.
