Not taking anything away from any issues that others may have experienced, just my own personal observations and experiences with Atomic Amps.
I've been familiar with Atomic Amps since their Reactor days when I used both active and passive wedges with the MB-50 for a couple of years. I bought a CLR active wedge when they first came, then an active Neo wedge and finally had my first CLR converted to a Neo.
During that time I've had to contact Atomic on two separate occasions regarding my amps. In the first instance regarding one of the Reactor wedges, I had sent an email to Atomic on a Saturday morning and ending up getting a phone call from Tom that same morning that solved the problem. Needless to say, I was pretty impressed with that level of customer service.
The second time I needed to contact Atomic about my CLR refit to a Neo, there was a small gap in our email communications. Since I had read on the forum that they had been experiencing some spam filter issues, I resent my response to Tom's email address along with the main Atomic email address which generated a response from Tom, who apologized for the email issues, and we were able to complete our business.
The bottom line for me is that I love how their amps have worked with all of the Axe-Fx incarnations I've had; Ultra, II and XL. Along with that, the customer service in my experiences has been top notch throughout my time of using Atomic Amps.
