Restoration
Prior to commencing any restoration, comprehensive measurements and a detailed structural analysis are conducted. Based on this analysis, a meticulous plan is drawn up to ensure the instrument is restored without compromising its original integrity.
Every step of the process is thoroughly documented with high-resolution photography. We maintain full transparency with the instrument owner throughout the journey, providing a complete and official record of the restoration.
Bass bar replacement and curb restorations
These procedures address some of the most common issues in instrument restoration. Over time, the soundboard loses its structural tension; installing a new bass bar provides essential support against string pressure and re-establishes optimal top-plate tuning for superior acoustic response.
Additionally, worn or thinned edges and purfling are painstakingly rebuilt using selected spruce and maple. This restores original timber thickness, ensuring the soundboard rests completely flat and securely on the ribs.
Top Soundboard Soundpost Cracks – Before
Cracks of this nature are frequently encountered and highly complex. Achieving a precise structural glue-joint is essential, and the subsequent varnish retouching must perfectly match the instrument’s original color and patina.
Top Soundboard Soundpost Cracks – After
Shown here is the soundboard soundpost crack after restoration. The crack has been securely glued and retouched, presenting a natural and seamless finish.
Top, Bottom, and Corner Block Replacement
Due to common deformations that occur over time—particularly in antique and historical instruments—the replacement of these structural blocks becomes essential.
Our Maintenance Process
-
Acoustic & Geometrical Measurement: Prior to removing the strings, full mathematical measurements and structural alignments are precisely documented.
-
Bridge Inspection & Replacement: String heights and bridge posture are thoroughly evaluated. If the current bridge is deformed or lacks proper height/arc, we recommend replacing it with industry-standard, top-tier bridge blanks such as Aubert Deluxe or Despiau Three-Tree (3-Tree).
-
Fingerboard Dressing & Conditioning: The fingerboard is planed and dressed to correct scoop and alignment, calibrated strictly to a 42 mm radius profile, and finished with protective oils for flawless playability.
-
Nut & Saddle Calibration: The upper nut and lower saddle are inspected, adjusted, and lubricated. String grooves are reshaped to ensure correct string clearance and smooth tuning action.
-
Peg Mechanism & Restoration: Pegs are inspected, cosmetically serviced, and fitted to guarantee smooth, slipping-free turning and reliable tuning stability.
-
Deep Cleaning: The instrument’s body and neck are entirely cleaned using our proprietary specialized varnish cream.
-
Varnish Retouching & Protective Polish: Surface dings or impacts are retouched to blend with the original color, followed by a clear protective polish application.
-
Seam Inspection & Repair: Open seams along the ribs and tables are thoroughly checked and glued using traditional hot hide glue where necessary.
-
Final Setup, Soundpost Adjustment & Play Testing: Fresh strings are installed, the instrument is brought to pitch, and an acoustic play test is conducted. If needed, the soundpost position is adjustedor a custom soundpost is carved from scratch to achieve optimal tonal balance and projection.
