Here's what Ken has to say about Knuckle Head:
"Knuckle head is the
brute force amp of the collection. His poweramp is
the main tone maker, it gives you a raunchy heavy
distortion or a nice crunchy yardbirds type tone.
Although it is capable of all the sounds in between.
I have only ever been able to get this distorted
sound from a real amp and no other amp sim has ever
been abe to give me the raunchy sort of distorted
high mid that this one does. With mid cranked,
Treble master cranked, bass 3/4, Treble off, master
1/4 everything else cranked, it will give you a
superb machine gun type of fast picking while riding
a string, like picking the e string really fast
while palm muting."
Brain bigger, better
brother. Inspired by some of the greatest amps ever,
Brain 2 is capable of some vintage sounds, smooth
blues, classic British crunch and things will get a
little hairy with the gain cranked, apparently.
AcmeBarGig suggests that if you're
in the mood for some Classic Rock tone, or want that
vintage crunch, then Brain 2 is your go to guy.
Brain 2 is not as evil and crushing as some of the
other amps but it still packs a huge punch and all
the while you can be confident in it's ability to
clean up and give you some great glassy clean sounds
with the gain and your guitar's volume rolled off a
