Servicing of most brass instruments is similar. For the purpose of showing an example, a trumpet has been used.
First, your instrument is inspected, to identify any existing problems. It is then dismantled to inspect all the components for future problems. Everything is checked; pistons/rotors, casings, guides, slides, receiver, felts, corks, springs, braces, linkages and any other components. Notes are taken to ensure nothing is missed.
Your instrument’s parts are then cleaned using appropriate tools, brushes and products, and it is dried. Silver / nickel / gold plated and lacquered instruments are all treated accordingly.Note:
if your instrument is particularly tarnished or dirty, or if there is excessive build up of green or dark deposits or corrosion inside, an extra charge will apply.Next, the list is referred to and any replacements or repairs are done. Minor alignments of tuning slides, correct lubrication and basic cleaning are included in the cost of your service. Your instrument is reassembled.
Notes: In a Service, repairs, lapping/polishing of valves, parts, springs, corks, felts and dents attract an extra charge. You will be notified in advance if the cost will be over $200 + GST. In a Major Service, lapping or polishing of valves, replacement of felt and cork components (and springs where needed), making stuck slides operational, aligning slides, and reducing minor denting by 95% is included.Your instrument is lubricated with appropriate lubricants and reassembled. Then it is tested, your case is vacuumed, and your instrument is returned.
