Jerome & Demet Style Tunenrs
Jerome tuner and Demet tuners are both reproduction sets made around the same time as Baker tuners and often very similar in design. Many of the Jerome tuners had very simple circular engraving around the wood-screw holes and signature style gears with no visible teeth. They often also have a ‘comb’ end design to the side-plates. The sets we make are based on this design with or without the gear cover disks.
The Demet tuners again often have very simple engraving with a unique end profile design only seen on these tuners.
Worm-wheel cover disks
These cover disks are made to fit with specially made gears and offer a slightly different look and feel to the tuners. Although not all Jerome tuners have these gears fitted, they are unique to these vintage sets. We have these disks in brass, nickel and aluminium (which when polished looks quite similar to polished sterling silver).
Although many (if not all) original tuners used ‘reversed gearing’, virtually all the sets we make now have the modern standard gears. However, if you are replacing a set from an original instrument, you may prefer the set made with the same gear orientation. Reverse gears are where the gearing is cut in the opposite direction and built with the gear (worm wheel) above the button shaft (worm). The button will maintain the same direction of rotation to tighten or loosen the strings. Please note, ‘cover disks’ are not currently available for reverse gearing.
Traditionally, Jerome and Demet tuners are fitted with the Kidney pattern buttons. Most customers now have the oval pattern since this is available in more material options.
If replacing an original tuner, please read the section on custom rollers here.
Most modern tuners are fitted with standard rollers with or without bearing bushes.
Demet Style Tuners
Very similar in design to the Jerome tuners, the Demet style is distinguished by the end profiles. These sets sometimes have 34mm string roller spacing which is unusual. This particular photo shows unusual ‘sleeves’ on the button shafts. We would not normally use this shape but prefer our standard sleeve design. Original tuners did not have anything on the shaft but a sleeve is required for our design of mechanism.
