2.4 Function Switch
“T” and “P1” positions mean that V2 is configured as a
triode (all even harmonics) or a pentode (odd harmonics).
“P2” 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
“P3” is a very distorted sort of pentode. Rectifying effects
can be obtained when lowering the bias and this can result
in what sounds like pitch change to the ear.
2.5 Filter
This is a low pass filter taking out frequencies above 7 kHz
at 12dB/octave.
2.6 Bypass
This switch links the input to the output directly, cutting out
the electronics of the Culture Vulture.
