Quick Links

The Tone Lifter is a flexible self-contained drop-in module designed for Strats and Strat-style guitars, without any physical
modifications to the instrument. Allowing numerous variations in sound, its bespoke stacked knob system is fitted in place
of the lower tone knob. In bypass, the pure passive signal is output. Pulling the upper knob gives control of mid boost, or
a combined bass/treble boost. The lower knob sets the frequency points for either mode. Power is provided by an internal
rechargeable battery system, which is charged via the jack socket.

  • Page 1 • Rechargeable battery system approximate dimensions: L40.5 X 19.0 X 19.0 mm (1.6” X 0.75” X 0.75”) • OPERATIONAL DESCRIPTION The Tone Lifter is based on a novel dual mode circuit which has a flat response setting, a conventional variable fre- quency mid range boost, as well as a combined bass/treble boost.
  • Page 2 Pull to ACTIVATE TONE CENTRE CLICK Activating the Tone Lifter with the upper knob set in its centre click, adds a little boost with a flat response. • BOOSTING THE MIDS • Pull the Upper Knob & and turn CW from centre click to set the boost level required.
  • Page 3 • PLUGGING IN THE CHARGER The Tone Lifter’s internal battery is charged via its jack socket, and it is important to follow this procedure when plugging it in. The Battery Pack will normally have some charge when new, but a full charge is recommended after installation.
  • Page 4 When setting out to install a Tone Lifter, 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.
  • Page 5 • Remove the top nut and dress washer, leaving the serrated washer and back nut on the jack. • Insert the Tone Lifter jack into the plate, fit the dress washer and then the top nut. Wind the nut on to the thread until the thread is just level with the front of the nut, for a neat finish.
  • Page 6 • Remove the top nut and washer from the Tone Lifter circuit board, leaving the back nut and washer on the pot thread. • Insert the Tone Lifter into the vacant hole in the pickguard, and fit the top washer and washer and nut. Tighten the top nut down until its top is just level with the top of the thread.
  • Page 7 Once all the wiring is complete, before re-fitting the pickguard, the following helps to confirm that the installation has been successful: • Make sure the Tone Lifter centre shaft is in its down position, and in the centre click. Turn down the volume on the guitar.
  • Page 8 • Rotate the outer shaft of the Tone Lifter and leave it set at roughly half its rotation, the exact setting is not at all crucial. Then drop the outer knob on to the shaft so that the pointer is pointing towards the pickups. Rotate backwards and forwards in order to locate the lugs in the knob onto the outer shaft of the pot, once located, push down.
