2.4 Function
Switch
“T” and “P1” positions mean that V2 is configured as a
triode (all even harmonics) or a pentode (odd harmonics).
All “PK” positions use the pentode configuration.
“PK1” to “PK5” have a sharp filter across the bias control
enabling the user to add a unique form of mid lift at
frequencies specially selected for musical effect.
“SQ1” is a very distorted sort of “pentode” and “SQ2” is a
more extreme version of the same (equivalent to “P2” in
the standard Culture Vulture).
“SQ3” is an exciting new discovery. It will sound quite
clean until overload is close when lots of harmonics are
suddenly added, and at higher levels over-compression will
occur and dynamics are inverted.
2.5 Presence
This switch works only on the 10dB setting end and is out
when at centre position . Up it adds +3 dB and Down +6dB
to the mid range, peaking at 3kHz.
The +10 switch itself adds a little extra top so one can
achieve a brighter ‘crunchier’ sound using this facility.
Compare by using the -10 dB switch next to the O/P pot.
2.6 Bypass
This switch links the line input to the output directly, cutting
out the electronics of the Culture Vulture. This switch is
designed to compare the Vulturised sound to the original.
It is disabled when the DI input is used. The processed
signal will always come up on Output Lo.
