USING THE TUNER OUTPUT
The  Bassbone  incorporates  a  separate  tuner  out.  This  output  passes 
through a band-pass filter to make it easier for a tuner to lock-on to the 
fundamental tone. Without the band-pass filter, some basses produce so 
many harmonics that the tuner is unable to lock-on and this causes the 
needle (or LED read out) to jump all over the place. Because the tuner 
out is separately buffered, the tuner circuit is completely removed from 
the primary audio signal path thus reducing its effect or added load on 
the circuit. 
TUNER MUTE
The power-boost  and  effects-loop 
features may be used to create 
a  tuner  mute  function  for  silent 
tuning. Insert an unterminated 1/4" 
"dummy" plug into the LOOP jack 
and set the BOOST ASSIGN switch 
to  LOOP.  With  this  arrangement, 
depressing the BOOST footswitch 
will  mute  the  Bassbones's  main 
output. If you intend to employ this 
mute  function  on  a  regular  basis, 
we  recommend  trimming  the  1/4" 
dummy  plug's  solder  posts  down 
and using it without the outter shell 
to save space.
USING THE XLR OUTPUT
The Bassbone is equipped with a separate XLR male output that acts like a 
direct box to feed a mixer. The 600-Ohm mic level output is designed to run 
along side microphone signals in a snake without causing crosstalk. 
It is important to note that unlike a 
direct box that would normally be 
connected before the Bassbone, 
the  XLR  out  is  post  Bassbone.  
This m eans t hat a l l  of  the 
Bassbone EQ and volume settings 
will be heard on the XLR output.  
This is particularly advantageous 
when playing gigs without a sound 
engineer as the bass signal going to the mixer will be boosted or altered 
to follow your Bassbone settings. An example would be on a solo where 
the engineer would normally increase the bass volume:  by engaging the 
Bassbone’s power booster, the level would increase on your bass amp 
and at the mixer at the same time. 
The XLR output is particularly handy in the studio for direct recording, 
as well  as  for  live  sistuations  where  bringing an  amplifier may  not  be 
practical. Simply connect the Bassbone’s XLR output to the mixer and 
use the Bassbone as your miniature amp. All your EQ settings are now 
right at your feet!
