OVERDRIVE
The overdrive gives distortion to the sound by highly increasing the pre-amplifier
input gain. The genuine tube circuitry allows a wide range of sound from unclipped
warm and clean to a hard distorted overdrive, by varying the amount of the overdrive
control.
[OVERDRIVE] Knob
This is for controlling the amount of overdrive of the tube amp circuit.
Controls the distortion amount. Full left is “clean”. The overdrive effect increases an you
rotate the knob.
NOTE: You can fine-set the overdrive. (P. 80)
TUBE AMP CIRCUIT
Tubes are rarely used in modern electric
apparatuses because semi-conductors
have better characteristics and tubes are
inferior in many aspects.
In the matter of sound production, the quali-
ties of a genuine tube preamp have not
been surpassed or duplicated.
In this organ, a real Tube circuit is used in
the preamp.
