BABY BABY BLUE - GETTING STARTED
Remove the AC cable from the accessory pack and connect it from the amplifier to a standard wall outlet.
Make sure that the "Gain" and "Master Volume" controls are set to the minimum position (fully counter-
clockwise). Locate the power switch on the right side of the front of the unit and turn the amplifier on.
Upon powering up, don't be surprised if you hear a small pop. This is absolutely normal.
Plug your instrument into the desired input jack (refer to "Front Panel Features" for greater detail). Turn
your instrument's volume up to at least 75% of maximum and slowly adjust the gain control. Once you
begin to play your instrument and you see the red light (marked "preamp clip") over the gain control
illuminate, back off the gain a bit. Now turn up the "Master Volume" and you should hear the sound of
your instrument amplified through the Baby Baby Blue. For more detailed information, please read the
entire manual carefully so that you can fully realize the potential of the your new Baby Baby Blue.

INPUT JACKS

Both input jacks accept a standard 1/4" phone plug and both inputs can be used at the same time.
Since the two inputs are totally independent, no loss in volume or tone will occur by using two
instruments simultaneously. However, the main applicational use for the two separate input jacks is their
difference in level, as the Passive/Active input has five times more gain than the Active input. In other
words, it's not necessarily intended as a "submixer" for two instruments, but no harm will come from
having two instruments plugged in at once. Please read below for more details.
PASSIVE/ACTIVE INPUT JACK
This input jack is designed to accommodate both "passive" instruments and most "active" instruments.
A passive instrument has no built-in preamp and does not use a battery, while an active bass utilizes a
battery-operated preamp for gain, tone controls, or both. The Passive/Active Input will work with all
instruments having a maximum output of less than 1 volt RMS. Some active pickups such as EMG,
Bartolini, etc., use batteries for operation and will work perfectly using this input. Instruments made by
MTD, Sadowsky, Modulus, etc., have active electronics that are suited for use in the Passive/Active
input.
Generally speaking, try this input first. If you hear a small amount of distortion and the preamp clip LED
is not activated, try using the Active input jack. If the Active input does not correct any audible distortion,
check the battery in your bass.
Note: If you would like to overdrive the first TUBE stage, this can be accomplished by using an exter-
nal preamp between your instrument and the Passive/Active input. To obtain optimum sound when
trying this, make sure the preamp clip LED is not activated. If this occurs, turn down your Gain con-
trol until the LED does not light. The first preamp tube stage is NOT monitored by the preamp clip cir-
cuit for this reason.
ACTIVE INPUT JACK
The Active input jack should be used with instruments having a built-in (on board) preamp or other sound
sources that will produce output levels greater than 1 volt RMS. The number of bass manufacturers has
increased significantly over the years, and it's impossible to try and keep track of them all. Generally, if
you have very "hot" pickups and/or tone controls installed in your instrument, and you use them to boost
the level of your bass signal 10 dB or more, you may find the Active input more compatible. The best
judge is your own ears.
If you're using a keyboard or bass pedal with the Baby Baby Blue, we have found the best choice to be
the Active input.
