Query: a bible for anyone interested in repairing instruments

If you are a keen repairer of woodwind instruments or just a player who wants to save a bit of money,this book is a diffinite buy. There are only three books in existance for this field, the second being Brands band Instrument Repair manual. Both of which are as useful as each other.If you work out the cost of having your instrument fixed over a few years, you will automatically see how much you can learn about your intrument and how much you can save.I refer to my copy as my bible and i am sure you will with yours in years to come.
