USING THE POWER BOOSTER
The BOOST control knob is designed to go from unity gain (full counter 
clockwise) to +8dB of gain boost (full clockwise). Depress the BOOST 
footswitch so the LED is illuminated and turn the BOOST control knob 
clockwise  until  the  desired  level  is  attained.  Check  the  relationship 
between the  two  channels  with  and without  the power-booster  to  fi ne 
tune your gain structure so there are no surprises when drepressing the 
footswitches.
USING THE EFFECT LOOP
The effect loop features an insert jack like the ones used on professional 
mixers. This employs a standard tip ‘send’, ring ‘return’ insert jack with a 
stereo TRS (tip ring sleeve) plug at one end and two standard ¼” mono 
plugs on the other.
The TRS plug connects to the Bassbone LOOP jack and the two ¼” mono 
plugs connect to the input and output jacks of the effect pedal.
The advantages of using an effect loop to connect pedals include reduced 
pick-up loading for a more natural bass guitar sound, less noise because 
your sound is going directly to your amplifi er and the ability to pre-set 
different  multi-pedal  setups  while  playing  without  actually  hearing  the 
setups until you engage the effect loop. 
Combining pedal effects with the power booster can be both powerful and 
dramatic. With the touch of a button, one can produce thunderous tones 
that can completely change the ambience from one song to another.  This 
will most assuredly spur on creativity!
