takes just a few minutes. The results are 
really good with just a little post-capture 
tweaking needed to get the taken global 
snapshot pretty indistinguishable from 
the real thing – whether that’s the sound 
of rig, or a single amp or dirt pedal setting. 
You can then store it in the QC, integrate 
it as a block into presets and maybe gig 
with it, without having to take the original 
equipment out of the house.
Sounds
The Quad Cortex is naturally responsive 
to play through and has some great-
sounding amps, with the usual familiar 
favourites covered. The actual modelled 
amps are variations on less than 20 guitar 
amps and a handful of bass amps, but 
these are supplemented with Neural 
Captures and, once you are part of the 
Neural community, there are loads of 
other users’ Captures available to load 
into your machine. There are effects in all 
categories, but not the variety you’d see 
in some rival floorboards; there’s no plate 
reverb, for instance. However, Neural says 
it is committed to expanding the amount of 
virtual devices and tells us there’s a major 
update on the way with significant changes 
and features.
Verdict
By now, you’ll all know the amount of 
different scenarios a unit such as this can 
be used in. Versatility is the name of the 
game and the Quad Cortex definitely has 
it. But does it outstrip the competition? 
Well, in certain ways… While its collection 
of models, particularly effects, is a work 
in progress (Neural is inevitably playing 
catch-up as other companies have been 
refining and adding to their hardware units 
for years), there is plenty of potential there. 
It has size and portability in its favour, 
its user-interface is outstanding, and the 
Neural Capture is an excellent facility. 
Overall, it’s a powerful addition that pushes 
the boundaries of the genre.  
Each footswitch has a 
rotary encoder that twists 
to adjust a parameter value
