I will. Though it'll be awhile for the Crackatwoa - maybe Feb or March. I'll be focusing more on customizing the look of that amp and am still learning to do some of the things I want to do to it. If you read a few pages back into the thread Doc offers up his thoughts on difference between the two. Which is the best description I've read anywhere. Unfortunately I've not been able to find a single review or decent set off impressions for the Crackatwoa outside of the one in the Bottlehead Forum. Reviews are even sparse for the mainline, outside of this forum, I've not found one. I do however see the mainline brought up in discussions where the primary focus is amps like the DNA Stratus and Eddie Current Zana Deux and being dismissed mostly because it has to be built. Anyway... will review the Mainline a couple weeks from now.
