2xEL34 + 4x6L6:
is the heavy artillery for large venues, extreme headroom or for any time you need to add unequaled power to
any of your sounds. This setting wires up all six power tubes to produce roughly 135 watts of crushing power and therefor, you may
find it hard to utilize in smaller rooms. In some cases the feel on the strings may be a bit stiff, or at least tighter at these lower relative
volumes because the power section is running at idle up until volume levels loud enough to need substantial room to breath.
However, when it comes time to play outdoor gigs or big stage venues, there is no mistaking the authority, punch and definition of this
mighty power section. A bolder version of the 2 + 2 combination, this scheme relies more on the 6L6's and therefor is a little richer in
character with slightly less emphasis on the top end than the harness with equal pentode representation.This makes for a sound that
has more midrange punch and low mid fatness and will work equally well for either clean rhythm or high gain lead sounds.
