Macro Tuners, Dual-Loaders and Sophia Drop Tuner Setup Guide

Intonation is adjusted by inserting a 2mm hex wrench into the Intonation Port next to the string slot to loosen, reposition and re-tighten in the normal manner.  Each Intonation Screw includes an additional hex socket accessed from under the base plate.

Deluxe Saddle Tailpiece Setup

  • Insert the supplied 2mm hex wrench into round hole at the apex of the saddle, turn counter clockwise to loosen locking mechanism.

  •  Insert plain end through rectangular opening, though the saddle and out over the string slot at the nose until the ball end resides within the rectangular port.   If string diameter is over .050-ish, insert 3/8 inch plain string end through nose slot and under clamp.

  • Use the 2mm hex wrench into round hole at the apex of the saddle to clamp string into a locked position

  • Add string to tuner and tension the string to pitch:)

60:1 Macro-tuner Setup Guide

Installing a string with the ball-end:

  • Tuner Knob -- 100% counter clockwise so String Lock is visible in slot

  • String Lock -- ensure 100% counter clockwise to receive strings

  • Push plain end of string through the Tuner Knob  string appears though the string slot until ball rests completely in the Tuner Knob.  Using your finger to create a slight bend you direct can be helpful.

  • Tighten String Lock Hex Screw to secure the string [clockwise].

  •  Reverse 1-4 to remove string

*******DO NOT TRY TO FORCE*******

Ensure the locking setscrew is threaded INWARDLY AT LEAST ONE TURN from FULL counter-clockwise before turning the Tuner Knob. 

Otherwise, it will be hard to turn within a half-turn or so…… and if you try overcome that resistance, you will jam the setscrew into the inner wall so it will not tune.

[We include a reminder] 


String Insertion Tips:

Optimal position for the tuner pin is forward where the lock strew is visible in the slot, in the position away from nut, and the lock is fully up [do not use the turner knob until the lock is engaged]  -- in some cases, adding a slight curve to the plain end of the string with you hands that you can direct is helpful.

For the same reason wound strings with a plain ends fair better , esp with a slight bend for some gages -- if you have wound strings without the plain end, there are two choices:

1).    From the above FULLY RETRACTED position [the internal level is loose], turn the lock screw ONE turn clockwise [be very careful] -- this closes the lock minimally but allows you to use the tuner knob to retract the tuner pin to improve the string angle going through the tuner pin to the string slot -- a slight bend in the end that you can direct while threading can speed the process.

2) Macro-tuners are dual loading -- insert 3/8" of the plain end [no-ball] of a string through the nose slot and under the string clamp, like vintage systems offer, and lock....

Alternative String Slot Sting Loading

Insert 3/8" wound string, up to .060 dia, or about .50 - .75” exposed core of a wound string  up to .070 dia, through the string slot and into the tuner pin deeply enough to  get the windings over the Intonation Point [IP] to clamp successfully.  That way, the cut end of the string is not sticking out of the back of either the Deluxe or the Macro-tuner knob.  The other end of the string is secured by a headpiece locking nut or tuning pegs with or without the ball-end.

On-the-Fly Intonation Adjustment:

  • Loosen tension in the string by the tuning peg

  • Use the Tuner Knob to thread the Tuner Pin, say .100/2.5mm, back to a second position -- see third figure below -- retune to pitch using tuning pegs

  • Unthread the Tuner Pin back to the first position, fully relaxing the string, to access the Intonation Screw

  • Loosen the Intonation Screw to adjust position, tighten and retune, verify, etc.

“Feel” Adjustable Determined By Tuner Pin Position:

Tuner Pin -- Tight feel/traditional fine tuning/tuning pegs -- small range -

Tuner Pin -- Looser feel/tuning pegs -- larger fine tuner range

Tuner Pin -- Min .250 range for headless usage and Intonation Adjustment

Tuner Pin -- Max .350 range for headless usage

Drop Tuner Setup Guide

Sophia Drop Tuner is a lever-based quick tuning accessory for the Macro-tuners... easily change from one pre-determined pitch to another, say, E to D on the 6th string, and then back again ... recommended with StopBlocks on the base model and the Stop Mode feature on the Global Tuner or with the Heavy Duty springs [HD} on the Global Tuner Pro or even the Coupling Stabilizer -- see below.

Flipping the Drop Tuner lever activates a cam to variably shift the position of the Tuner Pin and Tuner Knob assembly within the Macro-tuner body a pre-set amount.

Fine Adjustment Screw Setup

  • Drop Tuner lever in the closed or "E" position,  Back the 1.5mm setscrew out enough, if necessary, to ensure the macro-tuner Body and Lever Rings are fully closed.

  • Flip the Lever to "D"  position -- pointing away from the nut.

  • Make sure the string is stretched; and

  • The note is solid from big pulls from both directions.

  • Slowly turn the setscrew until you can feel that it has contacted the lever — this is the Start Point.

  • Turn the setscrew up to 3/4 + turn past the Start Point to create the .020 gap — a full turn is usually too much.

  • Flip the lever to the E Position, and use big pulls in both directions to check the "E" note.

This is our first rversion and seems pretty stable — the drop from the E position to the D position seems very accurate itself and the general tremolo pitch is good whilst floating!
Sometimes is takes big pulls when returning from the D position, please be mindful of this on the setup…

Sophia Tremolos offers several solutions to support adjacent string tension for drop tuning:

  • The built-in Adjustable Stop feature on the base model StopBlocks and Global Tuner can be setup to limit the tremolo so that the tremolo can not tilt back.

  • Global Tuner Pro -- includes pre-tensioned dual stabilizers in the spring block to reinforce initial position for accurate returns from both directions, double stops and drop tunings.

  • Using the Semi-Stabilizer to stabilize initial position for drop tunings along with double stops, etc. -- accurate recovery in one direction only.

Sophia Standard Saddles

Stainless Steel or Brass Dual-Loading Standard Saddles

Include a “top-loading” so that the reinforcement windings at the ball-end of the string advances to the .197 high intonation point -- to eliminate string stretch without resorting to locking or clamping the string --
Includes string threading through the spring block for a looser more traditional feel.Provides the option to install the string through the top to position the winding to the IP to utilize the windings as the reinforcement --  CNC Cold Rolled Steel Standard Tremolo Block found in the Sophia 2:22 Standard.


Sophia 2:22 Deluxe Saddles

Cast stainless steel Saddles -- Dual Locking/Loading

Like the Macro-tuners, these saddles provide the option to install and lock strings with the ball end in the trailing end - Larger diameter strings, up to approx .075" through the string slot.
