Schaller LockMeister 6 right Tremolo/Vibrato

Schaller LockMeister 6 Tremolo – a Made-in-Germany double-locking system

The Schaller LockMeister 6 right in Gold is a six-string double-locking tremolo engineered and CNC-machined in Germany. Since its 2012 debut, the platform has become Schaller's flagship locking-vibrato design, and the 2023/2025 Pitch Perfect update added individually selectable locking-nut and tremolo radii so the bridge can be matched to straight or compound fingerboards. The baseplate, saddles and locking nut are forged from hardened C45 steel, while the sustain block is cut from Pure Sound Brass — the same material combination that Schaller has produced for the original Floyd Rose since 1980.

What sets this tremolo apart in the locking-bridge category

Most locking tremolos ship with a single fixed saddle radius, forcing players to compromise between low-fret chord comfort and high-fret bending action. The LockMeister 6 solves this with five locking-nut radii (8″, 10″, 12″, 14″, 16″) and four tremolo radii (10″, 12″, 14″, 16″) — 14 combinations in total — plus height-adjusted one-piece steel saddles with fully closed bottoms that eliminate the shims and falling cover plates found on older designs. The 2025 update also extends the fine-tuner thread from M5 x 8 to M5 x 10 for a wider tuning range.

Construction and dimensions — built for tuning stability

Hardened-steel construction is the foundation of the LockMeister's tuning stability, because the harder the contact surfaces, the less the saddles and string-locking screws deform under string tension. The brass sustain block adds mass where it counts acoustically, and the 10 mm press-in bushings match international FR routing standards.

• Baseplate, Saddles and Locking Nut Material: hardened C45 steel — resists wear from string-locking screws and saddle movement.
• String Spacing (E to e): 54 mm — standard FR-style spacing that fits most pickup routs.
• Height-Adjustment Screw Spacing: 74.3 mm — matches international Floyd Rose routing.
• Press-In Bushing Size: 10 mm — direct drop-in for standard FR cavities.

Sustain block and string capacity — tonal mass for drop tuning

The brass sustain block is the single biggest contributor to the LockMeister's tone and sustain. Heavier blocks add low-end weight and reduce the "warble" of light blocks, and the three length options let players tune mass to scale length and tuning preference.

• Sustain Block Material: Pure Sound Brass — denser than zinc for stronger fundamental and longer sustain.
• Block Lengths Available: 32 mm / 37 mm / 42 mm — heavier blocks for lower tunings, lighter blocks for snappier response.
• Block Weight (37 mm): 119 g — adds focused low end without overbalancing the guitar.
• Maximum String Gauge: 0.080" / 2.03 mm — handles standard 6-string sets down to baritone low tunings.

Locking nut and fine tuners — the second half of the double-lock

The locking nut is CNC-milled from one-piece steel and ships in two widths (R2 = 41.4 mm, R3 = 42.9 mm) so it can be matched to nut-slot width as well as radius. Combined with the extended fine-tuner screws, the system holds pitch through heavy dive-bombs and pull-ups.

• Locking Nut Widths: R2 (41.4 mm) / R3 (42.9 mm) — fits common nut-slot widths.
• Locking Nut Radii: 8″, 10″, 12″, 14″, 16″ — matches straight or compound fingerboards.
• Fine-Tuner Screw: M5 x 10 (extended) — wider tuning range than the previous M5 x 8 design.
• Tremolo Radii: 10″, 12″, 14″, 16″ — saddle curvature matched to the fingerboard for clean bends.

Who the LockMeister 6 is built for

The Schaller LockMeister 6 right in Gold is the right choice for six-string electric-guitar players who want a Made-in-Germany locking tremolo with individually matched radii, a brass sustain block, and tuning stability under heavy whammy-bar use. It suits rock, metal, fusion and drop-tuning players who need a 54 mm E-to-e string spacing, a 10 mm bushing footprint, and a brass block heavy enough to anchor low tunings. It also fits luthiers and techs building or upgrading instruments with straight or compound-radius fingerboards, because the 14 radius combinations remove the usual compromise between low-fret chord feel and high-fret bending action. Players upgrading from a Floyd Rose 1000-series or a worn Korean import will find the hardened-steel construction and brass block a clear step up in sustain and tuning hold.

Schaller and the Floyd Rose legacy

Schaller has manufactured the original Floyd Rose tremolo in Germany since 1980, and the LockMeister is dimensionally and materially identical to the original — the same hardening process, the same C45 steel, the same brass sustain block. In 2020, Floyd Rose Marketing presented Schaller with a 40th-anniversary plaque recognizing the partnership. The LockMeister line debuted in 2012 as Schaller's own brand for this proven platform, and the 2023 Pitch Perfect update plus the 2025 extended fine-tuner screws are the latest in-house developments from the Postbauer-Heng engineering team.
