Master Level Control
This controls the final drive to the amplifier. Use this to control your stage
level. About mid point on the control should be normal for most playing
situations.
Compressor Active light
This indicates the activity of the compressor. When the LED lights up the
compressor is functioning.
Compressor/Limiter On/Off switch
This is located on the back panel of the original series and on the foot switch
in the (A) series currently in production.
This turns the Compressor limiter on and off to he final output stage of the
amplifier.
Damping Selector
This unique feature is on the foot switch of the current (A) model. It allows
the amplifier to be very flexible. In the low setting you get normal vacuum
tube damping response. That is an open round soft low end that works well
with 4 string Basses and traditional tones. In the hi position you get a tighter
more defined sound suitable for slapping and more modern playing styles.
Standby
This switch sets the amplifier in the standby mode. The filaments stay
powered up but the hi voltage to the output tubes is removed so that they can
not operate. This extends the life of the tube and allows for less stress during
start up and power down.
Mains On/Off
This turns the main power to the amplifier on and off.
