EBS-DP Billy Sheehan Signature Drive User Manual
BLOCK DIAGRAM
Thank you for purchasing the Billy Sheehan Signature Drive!
This pedal is a distillation of several important principles in the signal
chain for bass. Distorting a bass is always tricky. You can easily lose note
to note differentiation, as well as low frequencies. My solution for many
decades has been to run two signals, distort one, and re-combine (mix) after.
We managed to get this capability into a pedal with EBS. It does all that,
plus allows an unlimited possibility for pre-post mix tone shaping by
including a loop for each signal path.
The user can insert anything they wish within the loop for unique and
personally stylized tonality.
The pedal by itself sounds absolutely wonderful, but the feature of being
modified by the user’s choice of insert components makes it useful for anyone
playing any style.
It works perfectly.
THE CONTROLS
-
The Drive control sets the gain for the classic overdrive engine, all from
subtle to high gain tone. -
Use this control to fine tune the desired frequency scoop, ranging from lower to higher midrange.
-
This is the level control for the drive channel. This one is located post Drive Loop and before the final compressor.
-
This is the level control for the clean channel. This one is located post Clean Loop and before the final compressor.
INDICATOR LED
Indicates when the pedal is active.When the compression option is on, this LED also indicates dynamically the amount of compression. When this LED stops glowing you should replace the battery or check your power supply
FOOT SWITCH
Switches the pedal on or off.
HOW TO CHANGE BATTERY
- Carefully remove the four screws holding the bottom plate.
- Remove the bottom plate gently.
- Replace the old battery with a new one of the same type, 9V alkaline type; 6LR61.
- Gently place back the bottom plate, and make sure no cables are msqueezed. Attach the four mounting screws using moderate tension.
USING THE LOOPS
The Billy Sheehan Signature Drive pedal gives you the option of using
additional effects or units for the two channels independently before the
final mix level setting on the pedal.
When using the loops, use an insert cable of a standard TRS type, 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. This gives you the option of mixing different sources without necessarily using the send signal.
ADVANCED OPTIONS
By removing the bottom plate you get access to fine tune the settings for the compressor in the Billy Sheehan Signature Drive pedal.
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.
If you are not 100% sure on how to do this, please consult your nearest service center. Excessive force may result in damage to the unit, and the warranty in that case will be void.
TROUBLE SHOOTING GUIDE
Please consult the following checkpoints, before consulting one of the authorized EBS service centers.
| Checkpoint | Action if answered NO |
|---|---|
| Does the cable(s) work properly? | Replace cable(s). |
| Are the ¼” plugs properly connected all the way in? | Push the ¼” plugs all the |
way in
Are the Instrument cable(s) attached to the Right (input) jack, and the Amp
cable(s) connected to the Left (output) jack?| Reconnect input and output
jacks.
Does the pedal have a battery, and is the battery OK?| Put a new battery in
the pedal.
Does the indicator LED light when pressing the foot switch alternatively?|
Replace battery
Does the instrument work?| Check the instrument at your nearest service
center.
Does the amplifier work and is the volume turned up?| Turn up volume or check
the amp at your nearest service center.
If you are using a DC adapter, Are you using an EBS AD-9?| Check the voltage
and polarity of the adapter you are using.*
*EBS Sweden AB guarantees no error free operation when using other DC power supply than the EBS AD-9. Warranty is void if over-voltage has mbeen applied to the pedal.
