  • 3-dimensional adjustment of string height, intonation and string spacing (with roller bridge saddles).
  • Heavy and precise construction for extra long sustain.
  • Complete with 3mm or 4mm spacer.

All bridges are supplied with a 3mm baseplate as standard; alternatively, they can also be ordered with a 4mm baseplate.

Measure specifications

All measurements in the product catalogue are given in mm (inch), unless a different unit of measurement is stated.

 

Technical drawings and operating instructions

We do not accept any liability for the correctness of the technical drawings. Prior to installation, please measure for yourself once more, so you can consider regular manufacturing tolerances.

Please note that the technical data can also vary slightly, depending on the surface color. This is due to the difference in the galvanic coating and the galvanic layering, which depends on the color (nickel, chrome etc).

The technical drawings can be printed on one page width. Should the technical drawings not fit on one page, however, please check your print page setup (note: they can be several pages long).

From time to time, the measurements given in the file downloads on our website may differ from those given in the catalogue. Please bear in mind that the measurements given in the online downloads are current. Any discrepancies will be corrected when the catalogue is updated.

Allen Key

We use six different Allen wrenches to adjust the various screws on our bridges. The sizes for these are 1.27mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm and 3.5mm. The following table shows which Allen wrenches should be used for each type of bridge (all measurements are stated in mm):

FAQ

FAQ20010 I am a left-handed person, what do I need to consider with regard to Schaller bridges? Are they all suitable for left-handers without restrictions?

All Schaller bridges are suitable for left-handed guitars, with the exception of the "Hannes" and "STM". This is due to the diagonal arrangement of parts/saddles, which unfortunately cannot be altered.

FAQ20020 What do I need to do if I install a new bridge on my guitar and the existing drill holes are too large for the bushings included with the bridge?
We recommend filling in the drill holes and then re-drilling them - this also prevents unwanted resonance and movement. Any guitar maker should be able to do this for you.
FAQ20030 I would like to exchange my old bridge for a new one from Schaller. Unfortunately there will be unsightly holes from the old bridge. What can I do?
We include e.g. two blind screws with an LP tremolo, which cover the existing bore holes neatly and professionally. With other bridges and the same dimensions, changing or replacing is no problem at all.
FAQ20040 Do you also make bridges for 12-string guitars??
Sorry, we don't.
FAQ20050 Do you also make bridges with brass saddles?

No, we don't - or rather, only in part. These have not proven their worth in our experience. The roller saddles on our 3D-4, 3D-5 and 3D-6 bridges are made of brass.

FAQ20060 How does the Schaller fine-tuner (the tailpiece with the additional screws) work?

When stringing the guitar, please tune it as usual using the machine heads. Loosen the screws on the fine-tuner to the half-way point (or to the 3/4 point). When the guitar has been tuned using the machine heads, they can be more finely adusted as follows: Tightening the screw raises the pitch; loosening it lowers the pitch.

When making the initial adjustment, please allow the screws to protrude a little more than necessary (but not far enough to allow them fall out). This means they can be tightened accordingly during playing.

If this tightening results in the screws being tightened to the limit, please loosen them again and re-tune the string using the machine heads as usual. Then fine-tune again by tightening the screws once this has been done.

FAQ20070 I've heard that the Schaller bridges (e.g. GTM or STM), as with other manufacturers, only have one size of drive-in sleeves. What can I do?
Unfortunately, we cannot provide an appropriate sleeve for every imaginable size, and have thus decided to use only one size, i.e. the size that is used most frequently in the guitar industry. In these special cases, you should therefore contact a guitar maker who can work either with changes to the guitar body or with spacer sleeves.
FAQ20080 The Schaller 3D6 bridge has a screw on the treble side - what is this for?
You can use this screw to fix the string saddles in place so that they don't knock together and rattle when aggressive playing techniques are used.
FAQ20090 Can I fit Schaller's new "Hannes" bridge to any guitar?

Our Schaller "Hannes" bridge can be fitted to any guitar, provided that the body is flat at the point where the bridge is to be placed. Please find under Products/Product help/Hannes-Bridge. All information concerning Hannes-Bridge available.

FAQ20100 How is switching done on the pickups on the Schaller Piezo bridges?
There are no specific instructions for these Schaller bridges because the connection is in fact very simple.

You need to bring each of the 6 wires together in just one cable soldered with a jack socket or plug. (6x hosts and 6x cores together):

These cables can be fed directly into an amplifier or via an internal preamp.
There is also the option of feeding and switching the wires individually. This does make the whole thing more complicated, however, and is not necessary for "normal" use.
FAQ20110 Are the sounds individually picked up per saddle with the Schaller piezo bridges?
Yes, but normally they are combined to one line in a type-related way. If required, discuss other possibilities with a guitar maker or electrician.
