C.O.A.
Clean, Oil & Adjust.
Keep your clarinet in concert condition.
The essential maintenance that preserves the reliability, mechanical precision and acoustics of your clarinet in demanding professional life.

Small shifts, big difference.
Even with careful daily care, moisture, natural wear and changes in temperature slowly shift both the wood and the mechanism. You rarely notice it from one day to the next, until a passage no longer feels secure.
Mechanical precision
Minimal key play and balanced spring tension for a direct, reliable response, especially in rapid passages.
Tone & intonation
Clean tone holes and calibrated key heights for stable intonation and a free response in every register.
Wood protection
Professional oiling protects the wood against cracking and stabilises the microclimate inside the bore.
Signati optimisation
Selected worn pads are replaced with our own Signati pads for better reflection and reliability.
Six steps, one complete service.
Every C.O.A. follows the same thorough process in our Riga atelier.
Disassembly & assessment
Complete disassembly of the keywork. We check the wood for hairline cracks, the tenon corks, and the rods and pivots for play or bending.
Deep cleaning
Gentle cleaning of the body, tone holes and bore. Ultrasonic cleaning of all mechanical parts removes residue and old lubricants.
Wood care
Conditioning of the body with premium natural oils for deep impregnation.
Mechanism & pad service
- Cleaning and fresh lubrication of all rods, screws and pivots with long-lasting oils and greases
- Replacement of worn pads with our own Signati pads: up to 2–3 pads included
- Renewal of key corks and felts where necessary
Adjustment & regulation
- Precise regulation of all linked keys (e.g. F/C mechanism, ring keys)
- Optimised key heights for even intonation and tone colour
- Leak-light test and final air-tightness check under playing conditions
Play test
A final acoustic and response check across the entire range before your clarinet goes back to you.

If your clarinet needs a full repad or major work, our master-level overhaul is the right choice.

For orchestral musicians, teachers and frequent players we recommend a C.O.A. every 12 to 18 months. Regular fine-tuning stops mechanical wear and intonation drift before you notice them.
