Active/Passive Retro-Fit for P-Style Basses
• First plug the Special Jack Charger Adaptor into the guitar jack socket.
• Then plug the connector on the end of the charger output lead into the Special Jack Charger Adaptor.
• Lastly, plug the charger into an AC Mains socket and switch on.
• When charging is complete, switch off the charger at the AC Mains before unplugging the Special Jack Charger
Adaptor from the instrument.
• CHARGE STATUS INDICATOR
The Charge Status Indicator LED is wired directly to the internal battery. The LED is designed to be fitted either in its
panel mount holder, or left within the control cavity, when it is important to retain the original condition of the instrument,
without modification.
• The LED lit Red indicates the charging phase is in progress.
• The LED lit Green indicates that the charging phase is complete.
NOTE:
• It is not necessary to run the battery down completely before recharging, it can be topped up at any time.
• It charges more quickly during the initial charging phase, so even a short charge can be a useful top-up.
• From fully discharged to a full charge takes approximately 4 hours.
• P-RETRO INSTALLATION
• GENERAL
Fitting the P-Retro does not require any soldering skills, and the installation is reversible, in that it is often important to
be able to return an instrument to its exact stock configuration. This is especially important if a vintage instrument is
involved.
When setting out to install your P-Retro, make sure you have plenty of flat clear space on a table top or bench. Always
ensure that you have some soft material on that surface in order to protect the instrument, large fluffy towels are very
good for this.
Soft suede leather, such as a brand new chamois leather, is ideal as protection between the pickguard and the instru-
ment body. It is very soft, also very strong, and not easily pierced.
• REMOVAL OF THE ORIGINAL VOLUME & TONE CONTROLS
• Loosen and remove strings from their machine heads in order to gain free access to the pickguard.
• Remove all the screws from the pickguard and put them in a suitable container or other safe place.
• Lift off the pickguard and place upside down, making sure there is some soft but strong protection material between
the pickguard and the bass.
• Make a note or diagram as to where the wires in your bass are connected, so you have a guide in case you want to
return your bass to stock condition.
• Locate the wires from the pickup, usually a white and a black wire. The white or ‘hot’ pickup wire will normally be
connected to one of the tags on the volume control. The black or ‘cold’ pickup wire will normally be soldered to the
back of the volume pot. Cut these two wires close to the pot, leaving a few mm of insulation, which will help if ever
you want to restore the bass to stock.
• Cut any ground wires that are connected to the internal parts, again close to where they are connected. There is
