Should you have your old (woodwind) instrument repaired, or put the money toward a new one? Here are a few things to consider.
First, you should understand the difference between having “playing condition” repairs done and having a full overhaul done. The overhaul is an expensive service, often costing a significant percentage of what you would spend on a new professional instrument. A good overhaul will make your instrument play like brand new, or better. It generally includes any necessary repairs to the instrument’s body, straightening/realigning/refitting of keywork and tenons, replacement of all or most pads/corks/felts/springs, and thorough cleaning and lubrication. The overhaul makes sense about every 5-10 years for a well-made, professional quality instrument that you love and intend to play long-term. It’s generally not worth the money for a student-quality or so-called “intermediate” instrument.
Playing condition repairs are cheaper, à la carte services to get the instrument back into a baseline playable state, maybe replacing a few pads or corks as needed, or fixing anything that is broken enough to make the instrument unplayable. If you are low on cash, a good repair shop can help you prioritize what needs to be done within your budget. Even if you are playing your dream instrument and getting it overhauled on a regular schedule, playing condition maintenance is usually needed on at least an annual basis to keep things working well.
If your instrument is of less-than-professional caliber, or if you want qualities that your current instrument does not possess, you may be better served by having playing-condition work done for now, and saving toward a new instrument. Bear in mind that “professional” is a term applied by makers and retailers to sell instruments; if you’re not sure, it wouldn’t hurt to check in with a real professional (such as your private teacher) to see if what you are playing on is really suited to professional use.
If you are playing on an older professional model, you might want to explore the improvements made to more recent instruments, especially with regard to ergonomics, intonation, and evenness of tone. (Some musicians make these comparisons and decide to stick with what they’ve got, and that’s okay, too.)
A high-quality, well-maintained instrument makes playing easy and a pleasure, and the instrument’s career might even outlast yours.
