There’s an excellent overview in VGuitar Forums. Many thanks Shawn!
I couldn’t resist copying it to our blog, though of course it’s better to read it in the original source here.
I’ve been able to spend a few hours with this now, & figured I’d share my initial thoughts.

Learning the Unit & my First Preset:
I read the manual about 10 times before I “got” it.  No exaggeration – I have a highly annotated and dog-eared copy of the manual.  The way all the features work together is beautifully engineered, logical and highly intuitive.  The UI is unique, however, and has a learning curve.  Over time, you get to appreciate reading a lot of info at a glance, but this will take time and a healthy set of grey matter/memory.  (Having grown up in San Francisco in the ’60s and ’70s, I’m not sure I have the latter…)  
I spent most of my time thus far in “Menu 1”, the basic sound sculpting menu, learning the features & making a preset for jamming with my buddies.  The unit allows you to defeat the tone knob (Menu 1.10), and doing so creates a fuller sound that was more appealing to me.  I used a Peavey Wolfgang with nice hot pups and a set of 9s.   I suspect that lighter gauge strings like 9s may warrant defeating the tone stack.  
As much as I love hex distortion, you don’t want to overuse it.  Fortunately you can turn on processing of your mag pup signal (Menu 1.10).  Then you can mix a bit of your processed mag pups in via the Mono pot.  
THAT was an exciting discovery – the mix of hex distortion + some mag pup distortion to fill it out sounds fantastic.  
Since I was driving it from a GK3 mounted close to the bridge of my guitar, I used BOTH Root Boost circuits (Menu 1.7 & 1.8 ).  At the time, I was at home doing this at low volume…   
A note on the manual – it uses a notation of “0On_16Off” when describing Root Boost and Output Boost settings.  the “0” refers to the mono channel and the “16” refers to hex channels 1-6.  Thus, to affect your mono/mag pups and your hex processing, you would use the setting 0On_16On (red). 
First Jam:
I’ve been playing with my friends for years, using various gear & software, including a GR-55, a VG-99, tube amps, Amplitube, etc…  This was the first time my drummer said, “THAT thing is BADASS!”
You can’t really get a feel for this unit until you *feel* it live, at playing volume.   Continue reading “6Appeal First Impressions by Shawn”
