Preamp section features:
Active/Passive inputs:
Start by using the passive input. If your bass’s output distorts the input section, switch to
the active position. In the active input, a 12 db pad in the signal path will remedy the
situation.
Volume pot:
This pot controls the gain of the preamp section. Clean sounds are usually achieved by
setting the input gain around 11 or 12 o’clock. A little bit of musical distortion will occur
if set past one or two o’clock.
Tube EQ
:
Treble:
Tube driven shelving type, boosts up to 12 db. The center frequency is set at 4 kHz.
Bass:
Tube driven shelving type, boosts up to 12 db. The center frequency is set at 40 Hz.
Midrange:
Tube driven shelving centered at 400 Hz.
Deep Switch:
The deep switch adds 3db of broadband boost at 30 Hz.
Bright Switch:
This switch is a passive RC pre-emphasis circuit at 5-7 kHz. The bright switch will add a
brighter timbre to the entire range of your bass.
Effects Loop:
Send is push/pull for line or instrument level. This allows you to use a studio effects unit
(line level) or a stomp box (requires instrument level) in the FX loop.
