start here. Knobs off, nuts & washers off, side jack nuts
& washers off, now remove screws.
True to the Music
Spread chassis sides to clear input &
output jacks. Press on knobs with shafts counter-
clockwise and pointers at 7 o’clock.
TROUBLE SHOOTING
I am not getting any sound at all… Start by connecting your
guitar directly to your amplifi er & check each cable to make sure
they work. Make sure that these are plugged in correctly.
I am getting sound but no distortion… Make sure pedal is not
connected backwards by reversing the input and output. If ok,
check tube. If the problem persists, see your Tonebone dealer.
The LEDs do not light up… Check the power adaptor to make
sure it is plugged in. If the LEDs do not light up, check the outlet
with another device to make sure AC power is present. If they still
do not light up, there may be a problem - see your dealer.
The sound has changed, it sounds thin… The tube may need
changing. Bring it to your dealer to have him test to make sure.
I am getting radio signals though my amplifi er… Cables and
bad grounding are usually the cause. Check amplifi er is properly
grounded with a 3-prong A/C cord and wall receptacle is wired
correctly. Use high quality guitar cables with proper shielding.
