3. Carefully push the chassis bottom on, spreading the sides slightly
so as not to stress the side mounted ¼” input and output jacks.
4. Attach the side ¼” jack washers and nuts: Do not over-tighten
the plastic (for isolation) jacks as they strip easily! Attach the 4 chassis
screws (don’t over-tighten). Now you can tighten up the potentiometer
shaft nuts.
5. Re-install the knobs... first rotate the potentiometer shafts fully coun-
ter-clockwise. Place the knobs over the shafts so they point to 7 o’clock
and push straight down.
6. Test the pedal to make sure it works… plug in the power. The LED
should light when you depress the footswitch and you will see the tube
filament light up through the side vents.
Spread chassis sides to clear input &
output jacks.
Press on knobs with shafts counter-
clockwise and pointers at 7 o’clock.

8. Trouble shooting:
I am not getting any sound at all…
Start by connecting your guitar directly to your amplifier and checking
each cable to make sure they work. Then, make sure that these are
plugged in correctly.
I am getting sound but no distortion…
Make sure you have not connected the Tonebone backwards by revers-
ing the input and output. If connections are correct, check the tube. If the
problem persists, see your Tonebone dealer.
The LED does not go on…
Check the power adaptor to make sure it is plugged in. If the LED does
not light up, check the outlet with another device to make sure power is
present. If it still does not light up, check the power supply with a voltme-
ter or have your dealer check it.
The sound has changed, it sounds thin…
The tube may needs changing. Remove the tube and bring it to your
dealer to have him test it. If low, replace with a 12AX7.
I am getting radio signals though my amplifier…
Poor quality cables and bad grounding are usually the cause. Check
to make sure your amplifier is properly grounded with a 3-prong A/C
cord and that the wall receptacle is standard 3-prong duplex and wired
correctly. Make sure you are using high quality coaxial guitar cables with
proper shielding. Radial Tonebone pedals are engineered and tested to
ensure RF is eliminated as a source of noise.
