> Save money by tuning, regulating and repairing your own piano.
> Make extra cash by tuning for others.  Pianos have been around for
> years and will never be replaced.  Many used pianos can be found at
> good prices if you know what to look for.  We show you.  By spending
> a few dollars you can bring them up to first class quality and
> resell them for a good profit! You are taught how to tune with one
> tuning fork or a set of tuning forks.  Electronic tuning is
> explained together with instructions on how to build an expensive
> tuning fork amplifier with "Radio Shack " parts.  You do not need a
> "musical ear" to tune pianos.  Tuning is done, not by listening to
> musical tones, but by listening to beat sounds.  Knowledge of how to
> play a piano isn't required.  Besides tuning, you will learn how to
> make all the standard repairs and regulation that is common to old
> pianos.  A few special tools are required and you are instructed
> what and where to obtain tools and supplies.  This book is a bargain
> -- even if you only intend to tune your own piano.  However, most
> people have friends and belong to churches and organizations where
> pianos are common place.  Typically, these pianos are not tuned and
> regulated when they should be, which is at least twice a year.  You
> will now be able to fulfill a valuable and appreciated service to
> your church, etc.  Written in an easy to understand manner and your
> complete satisfaction is guaranteed.  Price includes Priority Air
> Mail shipping.  At this low price you no longer have an excuse not
> to add this new skill to your storehouse of knowledge.
