I am recent new owner of the Digitech GNX4, Before I made my purchase, I read the reveiws, only to find this thing has stirred up comments from extreme ends of the review spectrum, this thing seems to be hated as much as it is loved. With this being said I decided to go out on a limb and see for myself.
I am glad I did. It was exactly what I was looking for. I know there is alot of negative thought about all-in-one units, sure nothing beats a quality dedicated device, but let's face it not everyone has thousands & thousands of dollars to invest in all the equipment that is needed to come close to what the GNX4 is capable of. So even if some of the features aren't exactly dead on, it is still a lot of bang for the buck.
All in all, I must say that I am very impressed with the whole concept of the GNX4, and I am very happy my purchase. Let's see where this concept is at in the future, say 10 years,

I would be very interested in hearing the MESA TRIPLE RECTIFIER Patch
How can I hear it or possibly get it myself
