THANK YOU FOR PURCHASING
THE EBS BILLY SHEEHAN ULTIMATE SIGNATURE DRIVE PEDAL
Thank you for purchasing the Billy Sheehan Ultimate Signature Drive!
The ’Ultimate’ version has inherited all the features from the Deluxe
version (including the possibility to swap the drive chip without the
need of soldering). But the palette of sounds you can create is
expanded by the new Hi or Lo frequency filter that gives the Tone
control a much wider range.

amps and accessories.

ADVANCED CONTROL OPTIONS (as illustrated on next page)
BOOST FOOT SWITCH boosts the Drive gain level
when activated.
ACTIVE FOOT SWITCH Switches the pedal on or off.
REPLACEABLE OP-AMP CHIP - The chip can be removed and replaced
without need of soldering. Try a different 8-pin op-amp for a
different drive character. See EBS website for recommendations.
BOOST (trimmer) - Sets the level of the boost footswitch from +3 to
+10 d B
THR. (trimmer) - This control sets the threshold level for the
compressor. By turning this trimmer clockwise the threshold level
will be lower, i.e. the compressor will react at lower levels.
COMP (trimmer) - This control sets the amount of compression
when the compression mode switch is in the MID position.
NOTE: The factory setting for these trimmers is CENTER position.
POWER OPTIONS
DC POWER ADAPTOR We recommend the use of a DC Power Supply,
such as the EBS AD-9 Pro. The pedal handles 9-18 V DC, and
require a 2.1 mm pin center negative type of connector.
BATTERY The pedal can run on battery (not included). Use a 9V
alkaline type; 6LR61.

USING THE LOOPS
The Billy Sheehan Ultimate Signature Drive pedal gives you the option
to use additional effects to affect either the Clean or Drive channel
independently (the photo shows a reverb connected to the Drive Loop).
When using the loops, use an insert cable of a standard TRS type,
such as the EBS ICY-30, where the RING is the SEND signal, and the
TIP is the RETURN signal back to the pedal.
Note: You may also connect a mono plug directly into the insert jacks
without damaging the send output. Example: if your bass has separate
outputs for low and mid/high frequencies, you can use the Clean Loop
as an input for the lows and use the main input for the highs/mids.
