In addition to information about ruthenium you will also find further coating options consisting of a gold/ruthenium combination. You will find more information about the metal Ruthenium under News, Press and Service/Lexicon.


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

You can use string retainers from your general guitar parts supplier as an alternative to our string ferrules.
Here, you can find an overview of the three-dimensional adjustment options for our Schaller bridges.

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):

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.
Unfortunately, we don't produce 7-string or 12-string bridges. The Schaller 3D-8 bass bridge is available for 8-string guitars.
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, 3D-6 and 3D-8 bridges are made of brass.
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.
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.
Our GTM piezo bridge has a socket. Our other piezo bridge models do not.
Please take a look at our website under Products/Guideline/Bridges; here you can find a table listing the dimensions of the height adjusting screws.
All dimensions are given in our technical drawings, which can be found in the catalog and under Downloads.
No, that will not cause any problems. In relation to the narrow width of the fretboard, the difference between the 12" and the 14" radius is so small that there is no discernible difference.
It isn't possible to change these two bridges around without making changes to the instrument, as the distance between the height adjustment screws differs by 0.5 mm.
If necessary, we recommend sealing up the screw holes and then drilling new ones.
The Piezo elements are approximately 1.5 mm under the saddle. This means you can file in small grooves for the strings, but please do so with extreme care, in order to avoid damage to the piezos. Please also be aware that this modification may mean that not all piezo crystals are at the same distance from the respective string, which in turn may alter the sound of the instrument.
